3 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. The

Enable(/Disable) control function allows the system to

further extend the battery lifetime by reducing the

power consumption to virtually zero. This function

also incorporates an active discharge circuit on the

output for faster device shutdown. Where the fast

turnoff is not required the LP3999 linear regulator is

recommended. The LP3995 also features internal protection against short-circuit currents and

overtemperature conditions.

The LP3995 is designed to be stable with small 1-μF

ceramic capacitors. The small outline of the LP3995 DSBGA package with the required ceramic capacitors

can realize a system application within minimal board

area. Performance is specified for a −40°C to +125°C

temperature range.

The LP3995 is available in fixed output voltages from

1.5 V to 3.3 V, in DSBGA or WSON packages. For

other package options or output-voltage options,

contact your local TI sales office.
