Product Overview

The LT1763CDE#PBF is a 500mA low dropout Micropower Regulator featuring low output noise. The device is capable of supplying 500mA of output current with a dropout voltage of 300mV. Designed for use in battery-powered systems, the low 30µA quiescent current makes it an ideal choice. Quiescent current is well controlled, it does not rise in dropout as it does with many other regulators. With the addition of an external 0.01µF bypass capacitor, output noise drops to 20µVRMS over a 10Hz to 100kHz bandwidth. The LT1763 regulator is stable with output capacitors as low as 3.3µF. Small ceramic capacitors can be used without the series resistance required by other regulators. Internal protection circuitry includes reverse battery protection, current limiting, thermal limiting and reverse current protection. The parts come in fixed output voltages of 1.5, 1.8, 2.5, 3, 3.3 and 5V and as an adjustable device with a 1.22V reference voltage.
  • Low noise (20µVRMS, 10Hz to 100kHz)
  • Low quiescent current (30µA)
  • Wide input voltage range
  • Very low shutdown current (<1µA)
  • Low dropout voltage
  • No protection diodes needed
  • Fixed output voltages (1.5, 1.8, 2.5, 3, 3.3, 5V)
  • Adjustable output from 1.22 to 20V
  • Stable with 3.3µF output capacitor
  • Stable with aluminium, tantalum or ceramic capacitors
  • Reverse-battery protected
  • No reverse current
  • Over-current and over-temperature protected
