GENERAL DESCRIPTION

The ADPL44001 ultra-low quiescent current, highvoltage

linear regulator is ideal for use in industrial and

battery-operated systems. The device operates from a

4V to 40V input voltage, delivers up to 100mA of load

current, and consumes only 8μA of quiescent current at

no load. The device consumes only 0.9μA current when

in shutdown. Output voltage is adjustable in the 0.6V to

38V voltage range. Feedback voltage accuracy is ±2%

over temperature.

An open-drain PGOOD pin provides a power-good signal

to the system, achieving successful regulation of the

output voltage. The device also incorporates an enable

pin (EN) that allows the user to turn the part on or off.

The device has a thermal shutdown feature that shuts

down the part when the die temperature exceeds 165°C.

The ADPL44001 operates over the -40°C to +125°C

industrial temperature range and is available in a 6-lead,

compact TSOT and a 6-pin (3mm x 3mm) TDFN

packages.
