The Microchip MCP1804 is a family of CMOS low dropout (LDO) voltage regulators designed to deliver up to 150mA of current while maintaining a low quiescent current. It operates with an input voltage range from 2.0V to 28.0V and offers features like low dropout voltage, current limit protection, and a shutdown function. Suitable for applications such as cordless phones, notebook computers, digital cameras, and car audio systems, the MCP1804 provides a reliable power solution with a maximum output voltage tolerance of ±2%.
