MIC5253

100 mA Low Noise µCap LDO

Features

General Description

• Input Voltage Range: 2.7V to 5.5V

• 5-Lead SC-70 Package

The MIC5253 is an efficient, CMOS voltage regulator

optimized for ultra low noise applications. It offers 1.5%

initial accuracy, extremely low dropout voltage (165 mV

at 100 mA), and low ground current (typically 95 μA at

full load). The MIC5253 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.

• Ultra-Low Output Noise: 30 μV_(RMS)

• 100 mA Continuous Output Current, 150 mA

Peak Current

• Stable with Ceramic Output Capacitors

• Ultra-Low Dropout: 165 mV @ 100 mA

• High Output Accuracy:

Designed

specifically

for

handheld

and

- 1.5% Initial Accuracy

battery-powered devices, the MIC5253 provides a TTL

logic compatible enable pin. When disabled, power

consumption drops nearly to zero.

- 3.0% over Temperature

• Low Ground Current: 95 µA

The MIC5253 also works with low-ESR ceramic

capacitors, reducing the amount of board space

necessary for power applications, which is critical in

handheld wireless devices.

• TTL Logic Controlled Enable Input

• “Zero” Off-Mode Current

• Thermal Shutdown and Current Limit Protection

Applications

• Cellular Phones and Pagers

• Cellular Accessories

Available in a 5-lead SC-70 package, the MIC5253

offers a wide range of output voltages. Key features

include current limit, thermal shutdown, faster transient

response, and an active clamp to speed up device

turn-off.

• Battery-Powered Equipment

• Laptop, Notebook, and Palmtop Computers

• Consumer/Personal Electronics
