150mA Linear Voltage Regulator for Digital Applications

General Description

Key Specifications

n Input Voltage Range

n Output Voltage Range

n Output Current

n Output Stable - Capacitors

n Virtually Zero I_Q(Disabled)

n Very Low I_Q(Enabled)

n Low Output Noise

n PSRR

2.0 to 6.0V

0.8 to 3.3V

150mA

The LP3990 regulator is designed to meet the requirements

of portable, battery-powered systems providing an accurate

output voltage, low noise, and low quiescent current. The

LP3990 will provide a 0.8V output from the low input voltage

of 2V at up to 150mA load current. When switched into

shutdown mode via a logic signal at the enable pin, the

power consumption is reduced to virtually zero.

0.47uF

10nA

43uA

150uV_RMS

55dB at 1kHz

105us

The LP3990 is designed to be stable with space saving

ceramic capacitors as small as 0.47µF.

n Fast Start Up

Performance is specified for a -40˚C to 125˚C junction tem-

perature range.

For output voltages other than 0.8V, 1.35V, 1.5V, 1.8V, 2.5V, Package

2.8V, or 3.3V please contact your local NSC sales office.

All available in Lead Free option.
