Hot-selling and scarce MIC5255-2.5BD5 150mA Low Noise μCap CMOS LDO SOT23-5 spot stock

Product Descriptions

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.

The MIC5255 also works with low-ESR ceramic  capacitors, reducing the amount of board space necessary  for power applications, critical in handheld wireless  devices.

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-23-5, which offers the same footprint as the  standard IttyBitty® SOT-23-5, but only 1mm tall. The  MIC5255 offers a range of output voltages.
