MIC47053

500mA Micropower ULDO™

Linear Regulator

General Description

Features

The MIC47053 is a high-speed, adjustable output ultra-low

dropout, dual NMOS ULDO™ designed to power point-of-

load applications that require a low-voltage, high-current

power supply. The MIC47053 can source 500mA of output

current while only requiring a 1µF ceramic output capacitor

for stability. The MIC47053 offers 2% output voltage

accuracy over temperature, low dropout voltage (49mV @

500mA), and low ground current which makes this device

ideally suited for mobile and point-of-load applications.

 Wide input voltage range

– Input voltage: 1.0V to 3.6V

– Bias voltage: 2.3V to 5.5V

 Adjustable output voltage range down to 0.4V

 Low dropout voltage of 49mV at 500mA

 Low shutdown current: 0.1µA typical

 ±2% initial output voltage accuracy over temperature

 High bandwidth – very fast transient response

 Stable with a 1µF ceramic output capacitor

 Logic level enable input

The MIC47053 has an NMOS output stage offering very

low output impedance. The NMOS output stage makes for

a unique ability to respond very quickly to sudden load

changes such as that required by a microprocessor, DSP

or FPGA. The MIC47053 consumes little quiescent current

and therefore can be used for driving the core voltages of

mobile processors and post regulating a core DC/DC

converter in any processor.

 UVLO on both supply voltages

 Available in thermally-enhanced 2mm x 2mm Thin DFN

package

 Junction temperature range of –40C to +125C

The MIC47053 is available in the tiny 2mm x 2mm Thin

DFN packages with an operating junction temperature

range of 40C to 125C.

Data sheets and support documentation can be found on

Micrel’s web site at: www.micrel.com.

Applications

 Point-of-load applications

 PDAs, Notebooks, and Desktops

 DSP, PLD, and FPGA power supply

 Low-voltage post regulation
