FEATURES  
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 a space-saving, small 1µF ceramic capacitor.  
The LP3988 features an Error Flag output that  
indicates a faulty output condition.

5-Bump Thin DSBGA Package  
SOT-23-5 Package  
Power-Good Flag Output  
Logic Controlled Enable  
Stable with Ceramic and High-Quality  
Tantalum Capacitors  
The LP3988'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.  
•
•
Fast Turn-On  
Thermal Shutdown and Short-Circuit Current  
Limit  
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.

•
•
Input range: 2.5V to 6V  
Ooutput current: 150 mA  
PSRR at 10 kHz: 40 dB  
The device is ideal for mobile phone and similar  
battery powered wireless applications. It provides up  
to 150 mA, from a 2.5V to 6V input, consuming less  
than 1 µA in disable mode and has fast turn-on time  
less than 200 µs.  
Quiescent current when shut down: ≤ 1µA  
(Typical) Fast Turn-On time: 100 µs  
Typical dropout with 150 mA load: 80 mV  
Junction temperature range for operation:  
−40°C to +80°C  
The LP3988 is available 5 pin SOT-23 package and  
5-bump thin DSBGA package. Performance is  
specified for −40°C to +125°C temperature range and  
is available in 1.85, 2.5, 2.6, 2.85, 3.0 and 3.3V  
output voltages.
