MIC5247

150mA Low-Voltage µCap Linear Regulator

Preliminary Information

General Description

Features

The MIC5247 is an efficient, precise low voltage CMOS

voltage regulator optimized for ultra-low-noise applications.

TheMIC5247offersbetterthan1%initialaccuracy,and85µA

constant ground current over load (typically 85µA). The

MIC5247 provides a very low noise output, ideal for RF

applications where quiet voltage sources are required. A

noise bypass pin is also available for further reduction of

output noise.

• Ultralow noise

• Low voltage outputs

• Load independent, ultralow ground current: 85µA

• 150mA output current

• Current limiting

• Thermal Shutdown

• Tight load and line regulation

• “Zero” off-mode current

• Stability with low-ESR capacitors

• Fast transient response

• Logic-controlled enable input

Designed specifically for hand-held and battery-powered

devices,theMIC5247providesalogiccompatibleenablepin.

When disabled, power consumption drops nearly to zero.

Applications

• Cellular phones and pagers

• Cellular accessories

The MIC5247 also works with low-ESR ceramic capacitors,

reducing the amount of board space necessary for power

applications, critical in hand-held wireless devices.

Key features include current limit, thermal shutdown, a push-

pull output for faster transient response, and an active clamp

package, the MIC5247 also offers a range of fixed output

voltages.

• Battery-powered equipment

• Laptop, notebook, and palmtop computers

• PCMCIA V and V regulation/switching

• Consumer/personal electronics

• SMPS post-regulator/dc-to-dc modules

• High-efficiency linear power supplies
