MIC5248

150mA µCap CMOS LDO Regulator

w/Power Good

General Description

Features

The MIC5248 is an efficient, general purpose 1.2V CMOS

voltage regulator with a power good output function. The

MIC5248 offers better than 3%initial accuracy, and

constant ground current (typically 100µA) over load.

• Power Good indicator

• Load independent, ultra-low ground current: 100µA

• 150mA output current

• Current limiting

• Thermal shutdown

The MIC5248 also works with low-ESR ceramic

capacitors, reducing the amount of board space necessary

for power applications, critical in handheld wireless

devices.

• Tight load and line regulation

• “Zero” off-mode current

Key features include current limit, thermal shutdown, a

push-pull output for faster transient response, and an

active clamp to speed up device turnoff. Available in the

IttyBitty™ SOT-23-5 and the tiny 6-pin 2mm x 2mm MLF^®

package.

• Stability with low-ESR capacitors

• Fast transient response

• TTL-logic-controlled enable input

Applications

Data sheets and support documentation can be found on

Micrel’s web site at www.micrel.com.

• Processor power-up sequencing

• Laptop, notebook, and palmtop computers

• PCMCIA VCC and VPP regulation/switching
