The MIC5319-2.5BD5 is a linear voltage regulator from Quarktwin Technology Ltd. designed for high-performance applications requiring a low dropout voltage. It supports an input voltage range of 2.5V to 5.5V and provides a fixed output voltage of 2.5V with a maximum output current of 500mA. The device features an ultra-low dropout voltage of 200mV at full load, making it suitable for battery-operated devices. With a low ground current of 90µA and a fast turn-on time of 40µs, the MIC5319-2.5BD5 is efficient for portable electronics. It offers high power supply rejection ratio (PSRR) of up to 70dB at 1kHz and low output noise of 40µVRMS across a bandwidth of 10Hz to 100kHz. The regulator is stable with low ESR ceramic capacitors, which helps minimize board space and component costs. Additional features include thermal shutdown protection, current-limit protection, and a logic-controlled enable input pin. This product is suitable for applications such as cellular phones, PDAs, fiber optic modules, and audio codec power supplies. The MIC5319-2.5BD5 is available in compact package options, including a 2mm x 2mm DFN and a SOT23-5 package.
