ISL80102

High Performance 2A Linear Regulator

Product Status: Mass Production

OVERVIEW

The ISL80102 is a low voltage, high-current, single output LDO specified for a 2A output current. This LDOs operates from the input voltages of 2.2V to 6V and is capable of providing the output voltages of 0.8V to 5.5V.

An external capacitor on the soft-start pin provides adjustment for applications that demand inrush current less than the current limit. The ENABLE feature allows the part to be placed into a low quiescent current shutdown mode. A submicron BiCMOS process is used for this product family to deliver best-in-class analog performance and overall value.

This CMOS (LDO) consumes significantly lower quiescent current as a function of load over bipolar LDOs, so it is more efficient and allows packages with smaller footprints. The quiescent current has been modestly compromised to enable a leading class fast load transient response, and hence a lower total AC regulation band for an LDO in this category.
