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.

Then determine the maximum output current:
IOUT(MAX)
=
1.5478W
14V − 5V
= 172mA ⇒ IOUT(MAX)
=
50mA
Example 3 (TDFN Package):
TA = +50°C
VIN = 9V
VOUT = 5V
Calculate the maximum allowable package dissipation
at the given temperature as follows:
PD = 1.9048W
Find the maximum output current:
IOUT(MAX)
=
1.9048W
9V − 5V
=
476mA ⇒ IOUT(MAX)
=
50mA
In Examples 2 and 3, the maximum output current is
calculated as 172mA and 476mA, respectively; howev-
er, the allowable output current cannot exceed 50mA.
Alternately, use Figures 5a and 5b to quickly determine
the maximum allowable output current for selected
ambient temperatures and input voltages.
Output-Capacitor Selection
and Regulator Stability
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.
