产品描述

The LP3987 is a 150mA fixed output voltage regulator with very low dropout voltage designed specially to meet requirements of battery-powered applications. The additional sleep MODE feature will reduce current consumption during standby operation to prolong the usage of battery.

Dropout Voltage: 100mV maximum dropout with 150mA load.

Shutdown: Less than 1µA quiescent current.

Sleep Mode: Typically 14µA quiescent current during sleep MODE to reduce battery consumption.

Enhanced Stability: The LP3987 is stable with minimum 1µF±20% low ESR ceramic output capacitor as low as 5mΩ and high quality tantalum capacitors.

The LP3987 is available in a thin 5 Bump DSBGA package. Performance is specified for −40°C to 125°C.

This device is available with output voltage options of 2.5V, 2.6V, 2.8V, 2.85V, and 3.0V. For other voltage options, please contact Texas Instruments.
