The ISL80510 is a single output Low Dropout voltage regulator

(LDO) capable of sourcing up to 1A output current. This LDO

operates from input voltages of 2.2V to 6V. The output voltage

of ISL80510 can be programmed from 0.8V to 5.5V.

A submicron BiCMOS process is utilized for this product family

to deliver the best in class analog performance and overall

value. This CMOS LDO consumes significantly lower quiescent

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

translates into higher efficiency and packages with smaller

footprints.

State-of-the-art internal compensation achieves a very fast

load transient response and excellent PSRR. The ISL80510

provides an output accuracy of ±1.8 VOUT accuracy over all

load, line and temperature variation (TJ = -40°C to +125°C).

An external capacitor on the soft-start pin provides an

adjustable soft starting of the output voltage ramp to control

the inrush current. The ENABLE feature allows the part to be

placed into a low quiescent current shutdown mode.
