Microchip Technology, Inc. Voltage Regulators - Linear MIC5331-NNYMT-TR

The MIC5331-NNYMT-TR is a dual low dropout (LDO) voltage regulator from Quarktwin Technology Ltd., designed for applications requiring low power consumption and compact size. It operates within an input voltage range of 2.3V to 5.5V and can deliver up to 300mA output current per LDO. The device features a low quiescent current of 25µA per LDO, making it suitable for power-sensitive applications. This regulator boasts a high power supply rejection ratio (PSRR) of over 65dB, ensuring effective noise rejection, and has a low output voltage noise of 50µVRMS. The dropout voltage is minimal at 120mV under full load conditions, which enhances efficiency. The MIC5331 is stable with small ceramic output capacitors (as low as 1µF), allowing for reduced board space and component costs. The product is housed in a compact 8-pin 2mm x 2mm Thin DFN package, making it ideal for space-constrained designs such as mobile phones, camera phones, PDAs, and GPS receivers. It also includes thermal shutdown and current-limit protection features, enhancing reliability in various applications.
