2.5V and 4.096V Voltage References
Features
Description
• Precision Voltage Reference
The Microchip Technology Inc. MCP1525/41 devices
are 2.5V and 4.096V precision voltage references that
use a combination of an advanced CMOS circuit
design and EPROM trimming to provide an initial
tolerance of ±1% (max.) and temperature stability of
±50 ppm/°C (max.). In addition to a low quiescent
current of 100 µA (max.) at 25°C, these devices offer a
clear advantage over the traditional Zener techniques
in terms of stability across time and temperature. The
output voltage is 2.5V for the MCP1525 and 4.096V for
the MCP1541. These devices are offered in SOT-23-3
and TO-92 packages, and are specified over the
industrial temperature range of -40°C to +85°C.

Note 1: Output temperature coefficient is measured using a “box” method, where the +25°C output voltage is trimmed as close
to typical as possible. The 85°C output voltage is then again trimmed to zero out the tempco.
2: Output Voltage Hysteresis is defined as the change in output voltage measured at +25°C before and after cycling the
temperature to +85°C and -40°C; refer to Section 1.1.10 “Output Voltage Hysteresis”.

OUTPUT VOLTAGE DRIFT (TCVOUT)
1.1
Specification Descriptions and
Test Circuits
The output temperature coefficient or voltage drift is a
measure of how much the output voltage (VOUT) will
vary from its initial value with changes in ambient
temperature. The value specified in the electrical
specifications is measured and equal to:
1.1.1
OUTPUT VOLTAGE
Output voltage is the reference voltage that is available
on the output pin (VOUT).
1.1.2
INPUT VOLTAGE
EQUATION 1-1:
The input (operating) voltage is the range of voltage
that can be applied to the VIN pin and still have the
device produce the designated output voltage on the
VOUT pin.

DROPOUT VOLTAGE
1.1.9
LONG-TERM OUTPUT STABILITY
The dropout voltage of these devices is measured by
reducing VIN to the point where the output drops by 1%.
Under these conditions the dropout voltage is equal to:
The long-term output stability is measured by exposing
the devices to an ambient temperature of 125°C
(Figure 2-9) while configured in the circuit shown in
Figure 1-1. In this test, all electrical specifications of the
devices are measured periodically at +25°C.
EQUATION 1-2:
VDROP = VIN – VOUT
VIN = 5.5V
The dropout voltage is affected by ambient
temperature and load current.

MCP1541
VIN
VOUT
In Figure 2-18, the dropout voltage is shown over a
negative and positive range of output current. For
currents above zero milliamps, the dropout voltage is
positive. In this case, the voltage reference is primarily
powered by VIN. With output currents below zero
milliamps, the dropout voltage is negative. As the
output current becomes more negative, the input
current (IIN) reduces. Under this condition, the output
current begins to provide the needed power to the
voltage reference.

1.1.10
OUTPUT VOLTAGE HYSTERESIS
The output voltage hysteresis is a measure of the
output voltage error once the powered devices are
cycled over the entire operating temperature range.
The amount of hysteresis can be quantified by
measuring the change in the +25°C output voltage after
temperature excursions from +25°C to +85°C to +25°C
and also from +25°C to -40°C to +25°C.
1.1.5
LINE REGULATION
Line regulation is a measure of the change in output
voltage (VOUT) as a function of a change in the input
voltage (VIN). This is expressed as ΔVOUT/ΔVIN and is
measured in either µV/V or ppm. For example, a 1 µV
change in VOUT caused by a 500 mV change in VIN
would net a ΔVOUT/ΔVIN of 2 µV/V, or 2 ppm.
1.1.6
LOAD REGULATION (ΔVOUT/ΔIOUT)
Load regulation is a measure of the change in the
output voltage (VOUT) as a function of the change in
output current (IOUT). Load regulation is usually
measured in mV/mA.
1.1.7
INPUT CURRENT
The input current (operating current) is the current that
sinks from VIN to VSS without a load current on the out-
put pin. This current is affected by temperature and the
output current.
1.1.8
INPUT VOLTAGE REJECTION
RATIO
The Input Voltage Rejection Ratio (IVRR) is a measure
of the change in output voltage versus the change in
input voltage over frequency, as shown in Figure 2-7.
The calculation used for this plot is:

IVRR = 20log

VIN functions as the positive power supply input (or
operating input). An optional 0.1 µF ceramic capacitor
can be placed at this pin if the input voltage is too noisy;
it needs to be within 5 mm of this pin. The input voltage
needs to be at least 0.2V higher than the output voltage
for normal operation.
Normally connected directly to ground. It can be placed
at another voltage as long as all of the voltages shift
with it, and proper bypassing is observed.

Output Voltage (V

VOUT is an accurate reference voltage output. It can
source and sink small currents, and has a low output
impedance. A load capacitor between 1 µF and 10 µF
needs to be located within 5 mm of this pin.

APPLICATIONS INFORMATION
4.1
Application Tips
Mechanical stress due to Printed Circuit Board (PCB)
mounting can cause the output voltage to shift from its
initial value. Devices in the SOT-23-3 package are
generally more prone to assembly stress than devices
in the TO-92 package. To reduce stress-related output
voltage shifts, mount the reference on low-stress areas
of the PCB (i.e., away from PCB edges, screw holes
and large components).

applications.

OUTPUT FILTERING
CIN
If the noise at the output of these voltage references is
too high for the particular application, it can be easily
filtered with an external RC filter and op amp buffer.
The op amp’s input and output voltage ranges need to
include the reference output voltage.

VIN
As shown in Figure 4-1, the input voltage is connected
to the device at the VIN input, with an optional 0.1 µF
ceramic capacitor. This capacitor would be required if
the input voltage has excess noise. A 0.1 µF capacitor
would reject input voltage noise at approximately
1 to 2 MHz. Noise below this frequency will be amply
rejected by the input voltage rejection of the voltage ref-
erence. Noise at frequencies above 2 MHz will be
beyond the bandwidth of the voltage reference and,
consequently, not transmitted from the input pin
through the device to the output.

Output Noise-Reducing
The RC filter values are selected for a desired cutoff
frequency:
The load capacitance (CL) is required in order to
stabilize the voltage reference; see Section 4.1.3
“Load Capacitor”.

The MCP1525 and MCP1541 voltage references do
not require an input capacitor across VIN to VSS
However, for added stability and input voltage transient
noise reduction, 0.1 µF ceramic capacitor is
INPUT (BYPASS) CAPACITOR
The values that are shown in Figure 4-2 (10 kΩ and
1 µF) will create a first-order, low-pass filter at the
output of the amplifier. The cutoff frequency of this filter
is 15.9 Hz, and the attenuation slope is 20 dB/decade.
The MCP6021 amplifier isolates the loading of this low-
pass filter from the remainder of the application circuit.
This amplifier also provides additional drive, with a
faster response time than the voltage reference.

recommended, as shown in Figure 4-1. This capacitor
should be close to the device (within 5 mm of the pin).
4.1.3
LOAD CAPACITOR
The output capacitor from VOUT to VSS acts as a
frequency compensation for the references and cannot
be omitted. Use load capacitors between 1 µF and
10 µF to compensate these devices. A 10 µF output
capacitor has slightly better noise, and provides
additional charge for fast load transients, when
compared to a 1 µF output capacitor. This capacitor
should be close to the device (within 5 mm of the pin).

Typical Application Circuits
The MCP1525 and MCP1541 were carefully designed
to provide a voltage reference for Microchip’s 10-bit
and 12-bit families of ADCs. The circuit shown in
Figure 4-4 shows a MCP1541 configured to provide the
reference to the MCP3201, a 12-bit ADC.
4.2.1
NEGATIVE VOLTAGE REFERENCE
A
negative precision voltage reference can be
generated by using the MCP1525 or MCP1541 in the
configuration shown in Figure 4-3.

Reference.
In this circuit, the voltage inversion is implemented
using the MCP606 and two equal resistors. The voltage
at the output of the MCP1525 or MCP1541 voltage
reference drives R1, which is connected to the inverting
input of the MCP606 amplifier. Since the non-inverting
input of the amplifier is biased to ground, the inverting
input will also be close to ground potential. The second
10 kΩ resistor is placed around the feedback loop of
the amplifier. Since the inverting input of the amplifier is
high-impedance, the current generated through R1 will
also flow through R2. As a consequence, the output
voltage of the amplifier is equal to -2.5V for the
MCP1525 and -4.1V for the MCP1541.
