XC6223 | 300mA High Speed LDO Voltage Regulator
XC6223
The XC6223 series is a high speed LDO regulator that features high accurate, low noise, high ripple rejection, low dropout and low power consumption.
Overview
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 overcurrent 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.
