XC6701AF12MR-G

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

The XC6701AF12MR-G is a positive fixed-output low-dropout (LDO) voltage regulator manufactured by Torex Semiconductor using CMOS technology. It provides a stable 12V output with a maximum continuous current of 150mA. The device supports an input voltage range up to 28V and features a typical dropout voltage of 0.85V at 100mA load. Key electrical specifications include a quiescent current of 125µA, a power supply rejection ratio (PSRR) of 50dB at 1kHz, and line regulation of 0.15%/V. It operates within a temperature range of -40°C to +85°C and is housed in a compact SOT-25-5 surface-mount package.
