Brand: TOREX
Category: Voltage Regulator ICs

The XC6220B331MR-G is a highly accurate low noise high speed low dropout and large current CMOS Voltage Regulator with GreenOperation function. The XC6220 series consists of a voltage reference, an error amplifier, a current limiter, an inrush current prevention circuit, and a phase compensation circuit plus a driver transistor. With a 0.2R on-resistance driver transistor integrated and with output currents up to 1A, the ultra-low dropout voltage performance greatly extends battery life as does the GreenOperation function which can switch between high speed and power save modes automatically. Low ESR ceramic capacitors can be used for the output stabilization capacitor (CL). The output voltage is selectable in 0.05V increments within the range of 0.8 to 5.0V, using laser trimming technologies.


  1. Power Management
  2. Fibre Optics
  3. Audio


  1. Ceramic capacitor compatible
  2. Over-current protection circuit and a thermal shutdown circuit are built-in
  3. Over-current protection circuit will operate when the output current reaches its limit current
  4. The thermal shutdown circuit will operate when the junction temperature reaches its limit temperature
  5. The inrush protection circuit works by controlling the inrush current
  6. Any fluctuations to VIN caused by inrush current during system start-up can be minimized
  7. CE function enables the output to be turned off
  8. IC becomes a stand-by mode resulting in greatly reduced power consumption
