The XC6224 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, and a phase compensation circuit. This IC is suitable for a local power supply placed in adjacent to the system logic LSI or others, because of low input voltage operation, using an ultra small package USPN-4B02 (0.75mm x 0.95mm) and stable operation with a small phase compensation capacitor (CL) 0.47μF. Also, this IC has fast transient response and high ripple rejection (70dB @ 1kHz). 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 over current protection circuit is integrated and operates when the output current reaches current limit level.
The XC6224 Series is a high‑speed low‑dropout (LDO) regulator designed for local power supplies near system logic LSI. It operates from 1.2 V to 3.6 V, delivers up to 150 mA, and features low noise, high ripple rejection (70 dB @1 kHz), and an integrated current‑limit and short‑circuit protection circuit.
The device is offered in ultra‑small USPN‑4B02, SSOT‑24 and SOT‑25 packages and requires a 0.47 µF ceramic capacitor on both the input and output for stable phase compensation. The datasheet includes pin configurations, electrical characteristics, typical application circuits, and marking rules.
