Description

Features

The B4151 series are a group of positive output voltage,

five-pin regulators, which provide a high current even

when the input/output voltage differential is small. Low

power consumption and high accuracy is achieved

though CMOS and programmable fuse technologies.

Output voltage: 2.0V to 6.0V in 0.1V increments.

The B4151 consists of a high-precision voltage

reference, an error correction circuit, and a current

limited output driver. Key features include a Shutdown

Pin that reduces supply current. With good transient

responses, output remains stable even during load

changes.

The ON/OFF pin enables the output to be turned off,

resulting in reduced power consumption. Provided in

SOT-25 (150mW) packages minimizes the usage of

board real state.

• Maximum output current: 150 mA.

• Highly accurate: Output voltage +/- 2%(1%)

• Shutdown Supply Current 1µA

• Ground Current of Less than 20µA

• CMOS low power consumption.

0.20V at 160mA

0.38V at 80mA

• Small input/output differential:

• Shut Down Mode for Power Savings

• Improve pin-to-pin XC62GR-XX

• Pin-to-Pin Low Power to Bipolar LDO’s

Applications

• Battery Powered Equipment

• Notebook PC, Palmtops, PDA

• Portable Cameras and Video Recorders

• Reference Voltage Sources

• Cellular / GSM / PCS Phones
