GENERAL DESCRIPTION
The ADPL42001 ultra-low quiescent current, highvoltage
linear regulator is ideal for use in industrial and
battery-operated systems. The device operates from a
4V to 20V 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
18V 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 ADPL42001 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.
