XC6501B4120R-G

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

The XC6501B4120R-G is a high-speed, low-noise CMOS LDO regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 4.1V with a maximum output current of 200mA. The device operates within an input voltage range of 1.4V to 6.0V and features internal phase compensation, allowing for stable operation without an external load capacitor (CL). It includes a CE pin that enables stand-by mode with current consumption below 0.1μA. The part utilizes the USPN-4 package.
