300mA High Speed LDO Regulator with ON/OFF Switch

The XC6228 series is a high speed LDO regulator that features high accurate, low noise, high ripple rejection, low dropout and low power consumption. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a phase compensation circuit.

The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the seriesenables the electric charge at the output capacitor CL to be discharged via the internal switch, and as a result the VOUT pinquickly returns to the VSS level.

The output stabilization capacitor CL is also compatible with low ESR ceramic capacitors.
