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. The LP3992 also features short-circuit and
The LP3992 is designed to be stable with space-saving ceramic capacitors as small as 1
µF. Performance is specified for a –40°C to +125°C temperature range.
For output voltages other than 1.5 V, and for additional package options, contact
