40V, Ultra-Low Quiescent-Current
Linear Regulators in 6-Pin TDFN/8-Pin SO
6/MAX1507
General Description
Features
o Wide Operating Input Voltage Range (4V to 40V)
o Guaranteed 50mA Output Current
The MAX15006/MAX15007 ultra-low quiescent-current
linear regulators are ideal for use in automotive and
battery-operated systems. These devices operate from
an input voltage of 4V to 40V, deliver up to 50mA of out-
put current, and consume only 10µA of quiescent cur-
rent at no load. The internal p-channel pass device
keeps the quiescent current low even at full load. The
MAX15007 consumes only 3µA current when in shut-
down.
o Low Quiescent Current
10µA (No Load) and 90µA (Full Load)
o Operates Through Cold-Crank Condition
o Withstands 45V Load Dump
o Low Dropout Voltage of 300mV
(MAX15006B/MAX15007B)
The MAX15006A/MAX15007A have a fixed 3.3V output
while the MAX15006B/MAX15007B have a fixed 5V out-
put voltage. The MAX15007 includes an enable input to
turn the device on or off. All devices are short-circuit
protected and include thermal shutdown.
o Stable Operation with Tiny 2.2µF Output
Capacitor
o Enable Input (MAX15007)
o Preset 3.3V and 5.0V Output Voltages
o Thermal and Short-Circuit Protection
o -40°C to +125°C Operating Temperature Range
The MAX15006/MAX15007 operate over the -40°C to
+125°C automotive temperature range. These devices
are available in space-saving 3mm x 3mm 6-pin TDFN
and 8-pin SO thermally enhanced packages.

Detailed Description
driver. While in shutdown, the device consumes only
The MAX15006/MAX15007 high-voltage linear regula-
3µA (typ). EN withstands voltages up to 40V, allowing it
to be driven by high input level voltages or connected
to IN for always-on operation.
tors operate over a 4V to 40V input voltage range.
These devices guarantee 50mA load drive, and offer
preset output voltages of +3.3V or +5V. Thermal shut-
down and short-circuit protection prevent damage dur-
ing overtemperature and overcurrent conditions. The
MAX15007 includes an enable input (EN) allowing the
regulators to be turned on/off using a logic-level volt-
age. Driving EN high turns on the device while driving
EN low places the device in a low-power shutdown
mode. In shutdown, the supply current is reduced to
3µA (typ). The MAX15006/MAX15007 operate over the
-40°C to +125°C automotive temperature range. All
devices are available in thermally enhanced 6-pin
TDFN and 8-pin SO packages capable of dissipating
Thermal Protection
When the junction temperature exceeds +165°C, an
internal thermal sensor turns the pass transistor off, and
allows the device to cool. The thermal sensor turns the
pass transistor on again after the junction temperature
cools by 20°C. This results in a cycled output during
continuous thermal-overload conditions. Thermal pro-
tection protects the MAX15006/MAX15007 in the event
of fault conditions. Operation at T = +150°C without
J
going into thermal shutdown is not guaranteed. Use
Figures 3a and 3b to determine the minimum guaran-
teed output current.

Regulator
Output Short-Circuit Current Limit
The MAX15006/MAX15007 feature a 175mA current
limit. The output can be shorted to GND for an indefi-
nite period of time without damage to the device.
During a short circuit, the power dissipated across the
pass transistor can quickly heat the device. When the
die temperature reaches +165°C, the MAX15006/
MAX15007 shut down and automatically restart after
the die temperature cools by 20°C.
The regulator accepts an input voltage from 4V to 40V.
The MAX15006A/MAX15007A have a fixed 3.3V output
voltage while the MAX15006B/MAX15007B offer a fixed
5V output voltage.
EN Input (MAX15007 Only)
EN is an active-high, logic-level enable input that turns
the device on or off. Drive EN high to turn the device
on. An internal 0.5µA pulldown current keeps the
MAX15007 in shutdown mode when driven by a three-

The MAX15006/MAX15007 provide up to 50mA of con-
tinuous output current. The input voltage range extends
to 40V. Package power dissipation limits the amount of
output current available for a given input/output voltage
and ambient temperature. Figure 4 shows the maximum
allowable power dissipation for these devices to keep the
junction temperature below +150°C. Figure 4 assumes

Output-Capacitor Selection
and Regulator Stability
Example 3 (TDFN Package):
T = +50°C
For stable operation over the full temperature range
and with load currents up to 50mA, use a low-ESR
2.2µF (min) ceramic or tantalum output capacitor. Use
larger output-capacitor values such as 22µF to reduce
noise, improve load-transient response, and power-
supply rejection.

Some ceramic dielectrics exhibit large capacitance
and ESR variations with temperature. Ensure the mini-
mum capacitance under worst-case conditions does
not drop below 1.3µF to ensure output stability. With an
X7R dielectric, 2.2µF should be sufficient at all operat-
ing temperatures.

er, the allowable output current cannot exceed 50mA.
