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-μF 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 μA in disable mode and has fast turnon time

less than 200 μs.

The LP3988 device's performance is optimized for

battery-powered systems to deliver low noise, extremely low dropout voltage, and low quiescent

current. Regulator ground current increases only

slightly in dropout, further prolonging the battery life.

Power supply rejection is better than 60 dB at low frequencies and starts to roll off at 10 kHz. High

power-supply rejection is maintained down to lower

input-voltage levels common to battery-operated

circuits.

The LP3988 is available in a 5-pin SOT-23 package

and a 5-pin thin DSBGA package. Performance is specified for ?40°C to +125°C temperature range. For

all available output voltage and package options, see

the Package Option Addendum (POA) at the end of

the data sheet.
