Description

General part information

LP3988-Q1 Series

The LP3988-Q1 is a 150-mA low-dropout regulator designed specially to meet requirements of portable battery applications. The LP3988-Q1 works with a space-saving 1-µF ceramic capacitor. The LP3988-Q1 features an error flag-output that indicates a faulty output condition.

The LP3988-Q1 has performance 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. The device maintains high power-supply rejection down to lower input voltage levels common to battery-operated circuits.
