概要

Description

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.
