Micrel Expands Family of Ultra-Low-Dropout ICs in MLF Package

January 3, 2007

The MIC5302 and MIC5303 are targeted at ultra-thin portable applications, including imaging sensors for digital still and video cameras. In some cases, the components shrink the overall solution footprint by more than 50 %.


SAN JOSE, CA /PRNewswire-FirstCall/ -- Micrel Inc., an industry leader in analog, high-bandwidth communications and Ethernet IC solutions, launched a new family of single ultra-low dropout voltage (ULDO) linear regulators housed in a tiny 1.2 mm by 1.6 mm by 0.6 mm MLF package. The MIC5302 and MIC5303 shrink the solution footprint by more than 50 % when compared with 2 mm by 2 mm MLF and SC-70 packages. The devices are targeted at today's most demanding ultra-thin portable applications, including mobile phones, camera modules, imaging sensors for digital still and video cameras, PDAs, portable media players and PC cameras. Both devices are available immediately with pricing starting at $0.36 for the MIC5302 and at $0.42 for the MIC5303 in 1 K quantities.

"The tiny MLF packages in which Micrel has introduced these new products are comparable to chipscale packaging in size, with the added advantage of a 2-fold improvement in thermal performance," noted Ralf Muenster, Micrel's Director of Marketing for Power Products. "Micrel's new family of ULDO regulators has been launched at a time when portable designers are challenged to fit an overwhelming number of features into the sleekest form factors. Our new miniature voltage regulators provide designers with the flexibility to fit their power-supply needs into the smallest crevices left on their boards."

The MIC5302 and the MIC5303 are part of a new family of ultra-small single LDOs offering ultra-low dropout voltage of 50 mV@ 150 mA and 100 mV@ 300 mA, respectively. The devices offer more than 65 db power supply ripple rejection without the need for a bypass capacitor, saving both board space and cost. The MIC5302/03 achieves excellent transient performance with the use of a tiny 1 µF ceramic output capacitor. Additionally, the family of ICs features low-quiescent current (typically 85 µA), fast turn-on time (35 µs), and current limit and thermal shutdown protection, and it operates over a wide temperature range, from –40°C to 125°C.
