Texas Instruments LP3988QMFX-2P85

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.

The device is ideal for mobile phone and similar battery-powered wireless applications. It provides up to 150 mA, 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-Q1 is available in a 5-pin SOT-23 package, has performance specified for the −40°C to +125°C temperature range, and is available in a 2.85-V output voltage. For other voltage options, contact TI sales.
