LM27761DSGT Description


The LM27761DSGT 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. The low-cost capacitor LM27761DSGT is used in the application solution to provide up to 250 mA of output current. The regulated output for LM27761DSGT is adjustable between -1.5 V and -5 V. The LM27761DSGT operates at a 2-MHz (typical) switching frequency to reduce output resistance and voltage ripple. With an operating current of only 370 μA (charge-pump power efficiency greater than 80% with most loads) and a 7-μA typical shutdown current, the LM27761DSGT provides ideal performance when driving power amplifiers, DAC bias rails, and other high-current, low-noise voltage applications.



LM27761DSGT Features


  • 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-? Inverter Output Impedance, VIN= 5 V

  • ±4% Regulation at Peak Load

  • 370-μA Quiescent Current



LM27761DSGT Applications


  • Operational Amplifier Power

  • Wireless Communication Systems 

  • Cellular-Phone Power-Amplifier Biasing

  • Interface Power Supplies

  • Handheld Instrumentation

  • Hi-Fi Headphone Amplifiers

  • Powering Data Converters
