SAN JOSE, Calif. -- (March 16, 2004 ) A new micropower, ultra-low dropout regulator for applications in portable electronic devices such as cellular phone RF, is announced by Micrel Semiconductor (Nasdaq: MCRL), an industry leader in power management and high-speed communication ICs.
The MIC5305 is offered in a miniature, thermally superior 2mm x 2mm MLF™ package, and is also available in the Thin SOT-23-5 package for applications not as thermally demanding. When compared to a Thin SOT-23, the 2mm x 2mm MLF™ requires 55% less footprint and offers three times improvement in thermal resistance. "The MIC5305 is the world's highest performing 150mA LDO regulator," says Steve Knoth, LDO product marketing manager. "Its ultra-low dropout, high PSRR, and low ground current, coupled with low noise and fast turn-on time, make it ideal for demanding portable applications such as cellular phone RF." "Add to this the superior thermal performance of the MLF package, and you have an industry-leading solution for portable, space-sensitive applications," adds Knoth. When the devices are purchased in a quantity of 1,000, pricing for the MIC5305 in 2mm x 2mm MLF™ and Thin SOT-23-5 packaging starts at $0.74 and $0.66, respectively. Samples are available, and production quantities are stock to 8 weeks ARO. Summary of Features & Applications: MIC5305 150mA LDO in 2mm x 2mm MLF™ and Thin SOT-23-5 Packages Features

Fabricated in CMOS technology, the MIC5305 sets new standards in overall performance. It features PSRR of over 85dB at 1kHz and ground current of less than 90µA at full load of 150mA, offering the best ratio of PSRR/Ignd in the industry. It also has extremely low dropout of 60mV typical at 150mA, allowing for longer battery life in portable applications. The new device is the latest addition to Micrel's line of LDO regulators featuring µCap capability which allows the use of either ceramic or tantalum output capacitors.
