ISL80101AEVAL2Z開發(fā)板套件編程器的評估板-線性穩(wěn)壓器規(guī)格書PDF中文資料

The ISL80101A is a low dropout voltage, single output LDO

with programmable current limiting. This LDO operates from

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.

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.

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.
