信息

The LP3999 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. Ideally suited for powering RF/Analog devices this device will also be used to meet more general circuit requirements.

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 inclusion of an Enable(disable) control can be used by the system to further extend the battery lifetime by reducing the power consumption to virtually zero.

The LP3999 also features internal protection against short-circuit currents and over-temperature conditions.

The LP3999 is designed to be stable with small 1.0 µF ceramic capacitors. The small outline of the LP3999 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 device is available in DSBGA package.
