Microchip Technology, Inc. Voltage Regulators - Linear MCP1825S-0802E/AB

The MCP1825S-0802E/AB is a low dropout (LDO) linear voltage regulator capable of delivering up to 500 mA of output current. It operates within an input voltage range of 2.1V to 6.0V and provides a fixed output voltage of 0.8V. The device features a low dropout voltage of 210 mV at 500 mA, ensuring efficient performance in low voltage applications. With a typical quiescent current of 120 µA and a shutdown supply current of just 0.1 µA, the MCP1825S is suitable for battery-powered devices. It is stable with a minimum output capacitance of 1.0 µF, which helps reduce output noise and minimizes the overall size of the regulator solution. The MCP1825S also includes short circuit current limiting and overtemperature protection for enhanced reliability. This regulator is available in a compact TO-263-3 package, making it a practical choice for applications such as networking backplane cards, notebook computers, and other portable devices requiring efficient voltage regulation.
