MIC5255 - 150mA Low Noise UCap CMOS LDO

General Description

The MIC5255 is an efficient, precise CMOS voltage regulator optimized for ultra-low-noise applications.

It offers 1% initial accuracy, extremely-low dropout voltage (135mV at 150mA) and low ground current (typically 90µA).

Key Features

  • include current limit, thermal shutdown, faster transient response, and an active clamp to speed up device turn-off. Available in the 6-pin 2mm × 2mm MLF™ package, the IttyBitty® SOT-23-5 package and the new Thin SOT-235, which offers the same footprint as the standard IttyBitty® SOT-23-5, but only 1mm tall. The MIC5255 offers a range of output voltages. All support documentation can be found on Micrel’s web site at www. micrel. com. Features.

MIC5255 Micrel MIC5255 150mA Low Noise µCap CMOS LDO General Description The MIC5255 is an efficient, precise CMOS voltage regulator optimized for ultra-low-noise applications. It offers 1% initial accuracy, extremely-low dropout voltage (135mV at 150mA) and low ground current (typically 90µA). The MIC5255 provides a very-low-noise output, ideal for RF applications where a clean voltage source is required. A noise bypass pin is also available for further reduction of output noise. Designed specifically for handheld and battery-powered devices, the MIC5255 provides a TTL-logic-compatible enable pin. When disabled, power consumption drops nearly to zero.
