High Performance 1A Linear Regulator with Programmable Current Limiting

The ISL80101A is a low dropout voltage, single output LDO

Features

with programmable current limiting. This LDO operates from

• ±2% V

accuracy guaranteed over line, load and

T = -40°C to +125°C

input voltages of 2.2V to 6V, and is capable of providing output

voltages of 0.8V to 5V. Other custom voltage options are

available upon request.

ADJ

• Very low 212mV dropout voltage at V = 4.5V

A submicron BiCMOS process is utilized for this product family

to deliver the best-in-class analog performance and overall

value. The programmable current limiting improves system

reliability of end applications. An external capacitor on the

soft-start pin provides an adjustable soft-starting ramp. The

ENABLE feature allows the part to be placed into a low

quiescent current shutdown mode.

• High accuracy current limit programmable up to 1.75A

• Very fast transient response

• 100µV

output noise

RMS

• Power-good output

• Programmable soft-start

• Over-temperature protection

• Small 10 Ld DFN package

This CMOS LDO will consume significantly lower quiescent

current as a function of load compared to bipolar LDOs, which

translates into higher efficiency and packages with smaller

footprints. Quiescent current is modestly compromised to

achieve a very fast load transient response.

Applications

• Telecommunications and networking

• Medical equipment

• Instrumentation systems

• USB devices
