Micrel, Inc. Voltage Regulators - Linear MIC5330-SKYML

The MIC5330-SKYML is a dual ultra low-dropout (ULDO,Ñ¢) linear voltage regulator designed for portable electronics. It features two outputs, each capable of delivering 300mA, and operates within an input voltage range of 2.3V to 5.5V. The device exhibits a low dropout voltage of 75mV at 300mA, high power supply ripple rejection (PSRR) greater than 70dB at 1kHz, and ultra-low output noise of 30¬µV RMS, making it suitable for RF and noise-sensitive applications. Packaged in a compact 8-pin 2mm x 2mm leadless MLF¬Æ format, the MIC5330-SKYML occupies significantly less board space compared to traditional packages. It also includes features such as thermal shutdown protection, current limit protection, and a low quiescent current of 75¬µA per output. The device is rated for operation over a temperature range of -40¬8C to +125¬8C, ensuring reliability in various environments. This regulator is ideal for applications including mobile phones, PDAs, GPS receivers, and portable media players.
