µCap CMOS LDO Regulator w/Power Good

Final Information

General Description

Features

The MIC5248 is an efficient, precise CMOS voltage regulator

with power good output. The MIC5248 offers better than 3%

initialaccuracy,andconstantgroundcurrent(typically100µA)

over load.

• Power Good indicator

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

• 150mA output current

• Current limiting

• Thermal shutdown

• Tight load and line regulation

• “Zero” off-mode current

• Stability with low-ESR capacitors

• Fast transient response

• TTL-logic-controlled enable input

The MIC5248 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, a push-

pull output for faster transient response, and an active clamp

tospeedupdeviceturnoff.AvailableintheIttyBitty™SOT-23-5

package, the MIC5248 is a fixed 1.2V regulator.

Applications

• Processor power-up sequencing

• Laptop, notebook, and palmtop computers

• PCMCIA V and V regulation/switching
