DESCRIPTION

KEY SPECIFICATIONS

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.

•

2.5V to 6.0V Input Range

Accurate Output Voltage; ±75mV / 2%

60 mV Typical Dropout with 150 mA Load. V_out

> 2.5V

•

Virtually Zero Quiescent Current when

Disabled

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.

•

10 μVrms Output Noise Over 10Hz to 100kHz

Stable with a 1 μF Output Capacitor

Ensured 150 mA Output Current

Fast Turn-on Time; 140 μs (Typ.)

The LP3999 also features internal protection against

short-circuit

conditions.
