LP3992
Micropower 1.5V CMOS Voltage Regulator with
Shutdown Control
General Description
The LP3992 regulator is designed to meet the requirements
of portable, battery-powered systems providing an accurate
output voltage, low noise, and low quiescent current. Battery
life will be prolonged by the ability of the LP3992 to provide
a 1.5V output from the low input voltage of 1.9V. Additionally,
when switched to a shutdown mode via a logic signal at the
shutdown pin, the power consumption is reduced to virtually
zero. The LP3992 also features short-circuit and thermal-
shutdown protection.
The LP3992 is designed to be stable with space saving
ceramic capacitors as small as 1.0μF.
The device is available in an SOT23-5 package. Perfor-
mance is specified for a -40C to 125C temperature range.
For output voltages other than 1.5V and alternative package
options, please contact your local NSC sales office.
