Micrel intros ULDO regulator in ultrasmall package

Micrel Inc. has launched the MIC5301, a tiny ultralow dropout (ULDO) linear regulator. The chip is a single LDO offering an ultralow dropout of 40mV at 150mA, more than 75db power supply rejection ratio (PSRR) and ultralow output noiseall in an extremely compact form factor, the company said.

The MIC5301 is offered in a 1.6-by-1.6mm 6-pin MLF package. It is suited for cellular phones, RF power, camera modules, imaging sensors for digital still and video cameras, PDAs, portable media players (PMP) and PC cameras. The IC is currently available in volume, with pricing starting at 45 cents for 1,000 quantities for the 1.6-by-1.6mm 6-pin Thin MLF package.

"As battery voltages continue to drop in the vast majority of consumer products, maintaining high PSRR can present quite a challenge for designers," noted Ralf Muenster, Micrel's director of marketing for power products. "Micrel overcomes this by offering extremely low drop-out, preventing dropped calls and improving audio performance."

MIC5301 achieves efficient transient performance with the use of just one tiny and inexpensive 1?F ceramic capacitor. Additionally, it features low quiescent current, fast turn-on time (30?s), current limit and thermal shutdown protection and operates over a wide temperature range, from -40C to 125C.
