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. Should the application require a device with an active disable
function please refer to device LP3995.
The LP3999 also features internal protection against short-circuit currents and
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. For other package options contact your local TI
The device is available in fixed output voltages in the ranges of 1.5V to 3.3V. For
availability, please contact your local TI sales office.
