SNVS161E – OCTOBER 2001 – REVISED OCTOBER 2015 LP3988 Micropower, 150-mA Ultra-Low-Dropout CMOS Voltage Regulator
With Power Good
1 Features 3 Description The LP3988 is a 150-mA low dropout regulator
designed specially to meet requirements of portable
battery applications. The LP3988 is designed to work
with space-saving, small 1-ВµF ceramic capacitors.
The LP3988 features a Power Good (PG) output that
indicates a faulty output condition. The device is ideal
for mobile phone and similar battery-powered
wireless applications. It provides up to 150 mA output
current from a 2.5-V to 6-V input, consuming less
than 1 ВµA in disable mode and has fast turnon time
less than 200 Вµs. 1 Input Voltage Range: 2.5 V to 6 V
Output Current: 150 mA
PSRR at 10 kHz: 40 dB
Quiescent Current When Shut Down: ≤ 1µA
Fast Turnon Time: 100 Вµs (Typical) …
