The MICROCHIP TECH. MCP1700 is a family of CMOS low dropout (LDO) voltage regulators designed for applications requiring low quiescent current and efficient voltage regulation. It delivers up to 250mA of current while consuming only 1.6µA of quiescent current, making it ideal for battery-powered devices such as alarms, detectors, pagers, and cellular phones. The MCP1700 offers a wide input voltage range (2.3V to 6.0V), low dropout voltage (as low as 178mV), and standard output voltage options from 1.2V to 5.0V. It includes features like short circuit and overtemperature protection for robust operation.
