Microchip Technology, Inc. Voltage Regulators - Linear MIC5321-SLYMT-TR

The MIC5321-SLYMT-TR is a dual ultra-low dropout (ULDO,Ñ¢) linear voltage regulator designed for applications requiring high power supply rejection and low noise output. It operates within an input voltage range of 2.3V to 5.5V and provides two outputs, each capable of delivering 150mA. The device features a low dropout voltage of 35mV at 150mA, making it suitable for battery-powered devices. This regulator is housed in a compact 6-pin 1.6mm x 1.6mm Thin MLF¬Æ package, which offers excellent thermal performance and minimizes board space requirements. It is stable with a 1¬µF ceramic capacitor, ensuring compatibility with small form factor designs. The MIC5321 also includes a bypass pin for enhanced noise performance, a high power supply rejection ratio (PSRR) exceeding 75dB, and an ultra-low output noise of greater than 30¬µVrms. Additional features include low quiescent current of 150¬µA, fast turn-on time of 45¬µs, thermal shutdown protection, and current limit protection. This product is well-suited for use in mobile phones, PDAs, GPS receivers, portable electronics, and digital cameras, making it a versatile choice for engineers looking for reliable voltage regulation in compact applications.
