XC6701B452PR-G

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The XC6701B452PR-G is a positive voltage regulator IC from the XC6701 series, manufactured by Torex Semiconductor using CMOS process technology. It features a fixed output voltage of 4.5V with ±2.0% accuracy and supports an input voltage range of 2.0V to 28.0V. The device provides a maximum output current exceeding 150mA (with a 200mA limit) when VIN equals VOUT plus 3.0V. It incorporates a Chip Enable (CE) function for stand-by mode operation, reducing power consumption significantly. The regulator includes built-in over-current protection and thermal shutdown circuits.
