40V, Ultra-Low Quiescent-Current
Linear Regulators in 6-Pin TDFN/8-Pin SO
General Description
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.
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.
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Limits at -40°C are guaranteed by design.
Output voltage regulation is guaranteed for I

5µA.
Dropout voltage is defined as (V

) when V
OUT
is 2% below the value of V
OUT
when V
IN
= V
OUT
+ 3V.
For V

Note 5:
Enable to regulation time is the time the output takes to reach 95% of its final value with V
