LM27761 - Switched-Capacitor Voltage Inverter

Datasheet Summary

Description

The LM27761 low-noise regulated switched-capacitor voltage inverter delivers a very low-noise adjustable output for an input voltage in the range of 2.7 V to 5.5 V.

Four low-cost capacitors are used in the application solution to provide up to 250 mA of output current.

Features

  • 1 Inverts and Regulates the Input Supply Voltage.
  • Low Output Ripple.
  • Shutdown Lowers Quiescent Current to 7 µA (Typical).
  • Up to 250-mA Output Current.
  • 2.5-Ω Inverter Output Impedance, VIN = 5 V.
  • ±4% Regulation at Peak Load.
  • 370-µA Quiescent Current.
  • 2-MHz (Typical) Low-Noise Fixed-Frequency Operation.
  • 35-dB (Typical) LDO PSRR at 2 MHz With 80-mA Load Current.
  • 30-mV LDO Dropout Voltage at 100 mA, VOUT =.
