LP3995 Datasheet CMOS Voltage Regulator

Manufacturer: Texas Instruments

General Description

The LP3995 linear regulator is designed to meet the requirements of portable battery-powered applications, providing an accurate output voltage with low noise and low quiescent current.

Ideally suited for powering RF and analog devices, this device can also be used to meet more general circuit needs in which a fast turnoff is essential.

For battery-powered applications the low dropout and low ground current provided by the device allows the lifetime of the battery to be maximized.
