MIC5255

150 mA Low Noise µCap CMOS LDO

Features

General Description

• Input Voltage Range: 2.7V to 6.0V

• Thin SOT Package: 1 mm Height SOT-23-5

• Ultra-Low Output Noise: 30 µV_RMS

• Stability with Ceramic Output Capacitors

• Ultra-Low Dropout: 135 mV @ 150 mA

• High output accuracy:

The MIC5255 is an efficient, precise CMOS voltage

regulator optimized for ultra-low-noise applications. It

offers 1% initial accuracy, extremely-low dropout

voltage (135 mV at 150 mA) and low ground current

(typically 117 µA at full load). 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.

- 1.0% Initial Accuracy

- 2.0% Over Temperature

Designed speciﬁcally for handheld and battery

powered devices, the MIC5255 provides

TTL-logic-compatible enable pin. When disabled,

power consumption drops nearly to zero.

• Low Quiescent Current: 90 µA

• Tight Load and Line Regulation

• TTL-Logic-Controlled Enable Input

• “Zero” Off-Mode Current

The MIC5255 also works with low-ESR ceramic

capacitors, reducing the amount of board space

necessary for power applications, critical in handheld

wireless devices.

• Thermal Shutdown and Current-Limit Protection

Applications

• Cellular Telephones and Pagers

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 2 mm × 2 mm

VDFN package, the SOT-23-5 package and the Thin

SOT-23-5, which offers the same footprint as the

standard SOT-23-5, but is only 1 mm tall. The MIC5255

offers a range of output voltages.

• Cellular Accessories

• Battery-Powered Equipment

• Laptop. Notebook, and Palmtop Computers

• Consumer/Personal Electronics
