XC6501C1920R-G

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

The XC6501C1920R-G is a high-speed, low-noise CMOS LDO regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 1.9V 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 stable operation without an external load capacitor. It includes a CE pin for standby control, reducing supply current to less than 0.1μA. The component is housed in a USPN-4 package.
