Microchip Technology, Inc. Voltage Regulators - Linear, Low Drop Out (LDO) Regulators MIC5321-MKYMT-TR

The MIC5321-MKYMT-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 dual outputs of 150mA each. The device features an ultra-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 output capacitors. The MIC5321 also includes a bypass pin for enhanced noise performance, a fast turn-on time of 45¬µs, and built-in thermal shutdown and current limit protections. The operating temperature range for this part is from -40¬8C to +125¬8C, making it suitable for a variety of portable electronic applications, including mobile phones, PDAs, GPS receivers, and digital cameras.
