LP3981 Datasheet Micropower/ 300ma Ultra Low-dropout CMOS Voltage

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LP3981 Micropower, 300mA Ultra Low-Dropout CMOS Voltage Regulator March 2003 LP3981 Micropower, 300mA Ultra Low-Dropout CMOS Voltage.

General Description

The LP3981’s performance is optimized for battery powered systems to deliver ultra 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.

Key Features

  • n Small, space saving MSOP-8 n Low Thermal Resistance in LLP-6 package gives excellent power capability n Logic controlled enable n Stable with ceramic and high quality tantalum capacitors n Fast turn-on n Thermal shutdown and short-circuit current limit.
