XC6223 Series

ETR0339-005
Built-in Inrush Current Protection, 300mA High Speed LDO Voltage Regulator
■GENERAL DESCRIPTION
The XC6223 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, a thermal shutdown circuit and an inrush current protection circuit.
The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the series
enables the electric charge at the output capacitor CL to be discharged via the internal switch, and as a result the VOUT pin
quickly returns to the VSS level. The output stabilization capacitor CL is also compatible with low ESR ceramic capacitors.
The output voltage is selectable in 0.05V increments within the range of 1.2V to 4.0V which fixed by laser trimming
technologies. The over current protection circuit and the thermal shutdown circuit are built-in. These two protection circuits
will operate when the output current reaches current limit level or the junction temperature reaches temperature limit level.
