SNVS192C – OCTOBER 2002 – REVISED NOVEMBER 2015 LP3992 Micropower 1.5-V CMOS Voltage Regulator With Shutdown Control
1 Features 3 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. The LP3992 also features shortcircuit and thermal-shutdown protection. 1 Input Voltage: 1.9 V to 5.2 V
Operation From a Low Input Voltage: 1.9 V
Accurate Output Voltage: 1.5 V В± 0.09 V
Quiescent Current in Shutdown: < 1.5 ВµA
Stable With an Output Capacitor: 1 ВµF
Ensured Output Current: 30 mA
Low Output Voltage Noise: 300 ВµVRMS
Low Quiescent Current: 29-ВµA Typical …
