XC6233Series
ETR03066-004
200mA High Speed LDO Voltage Regulator with Inrush Current Prevention
■GENERAL DESCRIPTION
The XC6233 series is a 200mA high speed LDO regulator that features high accurate high ripple rejection and low dropout. The
series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a phase compensation circuit and an
inrush current prevention circuit.
The output voltage is selectable in 0.05V increments (Accuracy ±1%) within the range of 1.2V to 3.6V.
The CE function enables the circuit to be in stand-by mode as well as the electric charge at the output capacitor CL to be
discharged via the internal switch, and the VOUT pin quickly returns to the Low level.
The series is also compatible with low ESR ceramic capacitors, which provides stable output voltage. This stability can be
maintained even during load fluctuations due to the excellent transient response.
The over current prevention circuit will operate when the output current reaches the current limit.
