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 is prolonged by the ability of the LP3992 to provide a 1.5-V output from the low input voltage of 1.9 V.

Additionally, when switched to a shutdown mode via a logic signal at the enable (EN) pin, the power consumption is reduced to virtually zero.
