LP5951 - Low-Dropout CMOS Voltage Regulator

General Description

The LP5951 regulator is designed to meet the requirements of portable battery-powered systems providing a regulated output voltage and low quiescent current.

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

Key Features

  • 1 Input Voltage Range: 1.8 V to 5.5 V.
  • Output Voltage Range: 1.3 V to 3.7 V.
  • Excellent Line Transient Response: ±2 mV (typical).
  • Excellent PSRR:.
  • 60 dB at 1 kHz typical.
  • Low Quiescent Current of 29 µA typical.
  • Small SC70-5 and SOT-23-5 Packages.
  • Fast Turnon Time of 30 µs typ.
  • Typical < 1 nA Quiescent Current in Shutdown.
  • Ensured 150-mA Output Current.
  • Logic Controlled Enable 0.4 V/0.9 V.
  • G.
