■GENERAL DESCRIPTION

The XC6207 series are precise, low noise, high speed, and low dropout regulators with green operation (GO) function. They are

fabricated using Torex’s CMOS process. Performance features of the series include high ripple rejection and low dropout

voltage, and the series include a reference voltage source, an error amplifier, a current limiter, and a phase compensation

circuit. Output voltage is selectable in 50mV increments within a range of 1.2V~5.0V, using laser trimming technologies. The

operation, low power consumption and high efficiencies by automatically switching between a high speed mode (HS) and a

power save mode (PS) depending upon the load current level. The switching point of the GO to the output current is being

fixed inside the IC. The IC operates when the GO pin is low-level. When only high-speed operation is required, it can be fixed

by inputting a high level signal to the GO pin, thus providing operating conditions with the most suitable level of supply current

for the application. The CE function enables the output to be turned off resulting in greatly reduced power consumption. In

also operate as a short circuit protection for the output current limiter and the output pin.
