General Description

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

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 allows the system to further extend the battery lifetime by reducing the power consumption to virtually zero.

The Enable(/Disable) function on the device incorporates an active discharge circuit on the output for faster device shutdown.

The LP3995 also features internal protection against short-circuit currents and over-temperature conditions.

The LP3995 is designed to be stable with small 1.0 µF ceramic capacitors. The small outline of the LP3995 micro SMD 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 device is available in micro SMD package and LLP package. For other package options contact your local NSC sales office.

The device is available in fixed output voltages in the ranges 1.5V to less than 1.8V and 1.8V to less than 2.5Vand 2.5V to 3.3V. For availability, please contact your local NSC sales office.
