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 circuit's power consumption to be reduced to 0.1μA, thus prolonging the battery life.
The XC6223 series from Torex is a high‑speed low‑dropout (LDO) voltage regulator featuring built‑in inrush current protection, current limit, short‑circuit and over‑heat protection. It supports output currents up to 300 mA, input voltages from 1.6 V to 5.5 V, and selectable output voltages between 1.2 V and 4.0 V in 0.05 V steps.
The device includes a CE pin for standby control, low‑ESR capacitor compatibility, and a low standby current of 0.1 µA. It is RoHS‑compliant and offered in several small packages such as USPQ‑4B03, USP‑4, SSOT‑24, SOT‑25 and SOT‑89‑5.

The XC6223 series can deliver up to 300 mA of output current.
It operates with an input voltage between 1.6 V and 5.5 V.
A built‑in inrush current protection circuit limits the inrush current from VIN to VOUT during start‑up.
The standby (stand‑by) current is 0.1 µA.
