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”.

The dropout voltage of these devices is measured by

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.

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.

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).

OUTPUT FILTERING

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 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.

The MCP1525 and MCP1541 voltage references do
not require an input capacitor across V to V
INPUT (BYPASS) CAPACITOR
The values that are shown in Figure 4-2 (10 k 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.

However, for added stability and input voltage transient
noise reduction, 0.1 µF ceramic capacitor is
a
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 V
to V
acts as a

OUT
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
NEGATIVE VOLTAGE REFERENCE
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
A
negative precision voltage reference can be
generated by using the MCP1525 or MCP1541 in the
configuration shown in Figure 4-3.

FIGURE 4-4:

FIGURE 4-3:
Negative Voltage
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 R , which is connected to the inverting
1
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 k resistor is placed around the feedback loop of
the amplifier. Since the inverting input of the amplifier is
high-impedance, the current generated through R will
1
also flow through R . As a consequence, the output
2
voltage of the amplifier is equal to -2.5V for the
MCP1525 and -4.1V for the MCP1541.
