MAX15006/MAX15007
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 output
current, and consume only 10μA of quiescent current 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 shutdown.
The MAX15006A/MAX15007A have a fixed 3.3V output
while the MAX15006B/MAX15007B have a fixed 5V
output voltage. The MAX15006C/MAX15007C feature
an adjustable output from 1.8V to 10V. 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.

Note
2: Limits at TA = -40°C are guaranteed by design.
3: Output voltage regulation is guaranteed for IOUT ≥ 5μA.
4: Dropout voltage is defined as (VIN - VOUT) when VOUT is 2% below the value of VOUT when VIN = VOUT + 3V.
5: For VOUT = 3.3V, the 700mV dropout indicates VOUT does not reach 2% below VOUT at VIN = VOUT + 3V at minimum 4V
input voltage.
Note 6: Enable to regulation time is the time the output takes to reach 95% of its final value with VIN = 14V and EN is taken from
VIL to VIH in 5ns.

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. The MAX15006C/MAX15007C feature
an adjustable voltage output by connecting an external
resistive divider from OUT to FB and to GND (see the

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 protection
protects the MAX15006/MAX15007 in the event of fault
conditions. Operation at TJ = +150°C without going into
thermal shutdown is not guaranteed. Use Figures 3a and
3b to determine the minimum guaranteed output current.
Output Short-Circuit Current Limit
The MAX15006/MAX15007 feature a 175mA current limit.
The output can be shorted to GND for an indefinite 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

Regulator
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-state driver
in high-impedance mode, or an open-drain driver. While
in shutdown, the device consumes only 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.
OUTPUT CURRENT (mA)
The MAX15006/MAX15007 high-voltage linear regulators operate over a 4V to 40V input voltage range. These
devices guarantee 50mA load drive, and offer preset
output voltages of +3.3V (MAX15006A/MAX15007A) or
+5V (MAX15006B/MAX15007B) or an adjustable voltage
output from 1.8V to 10V (MAX15006C/MAX15007C).
Thermal shutdown and short-circuit protection prevent
damage during overtemperature and overcurrent conditions. The MAX15007 includes an enable input (EN)
allowing the regulators to be turned on/off using a logiclevel voltage. 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 1.904W and 1.509W at
TA = +70°C, respectively.

After determining the allowable package dissipation,
calculate the maximum allowable output current, without
exceeding the +150°C junction temperature, using the
following formula:
where VFB = 1.23V and a 5μA minimum current is
required in the external divider for stability.
Available Output Current Calculation
The MAX15006/MAX15007 provide up to 50mA of continuous 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 5 shows the maximum
allowable power dissipation for these devices to keep the
junction temperature below +150°C. Figure 5 assumes
that the exposed metal pad of the MAX15006/MAX15007
is soldered to 1in2 of PCB copper.
Use Figure 5 to determine the allowable package dissipation for a given ambient temperature. Alternately, use the
following formulas to calculate the allowable package dissipation. For the TDFN package:

allowable output current cannot exceed 50mA.

Then determine the maximum output current:

=

Example 3 (TDFN Package):

VOUT = 5V
Alternately, use Figures 6a and 6b 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 outputcapacitor 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 minimum
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 operating temperatures.

the given temperature as follows:
