ISL80505IRAJZ

Intersil ISL805xx High-Performance Low Dropout Voltage Regulator is a single output Low Dropout voltage regulator (LDO) capable of sourcing up to 1A output current. The output voltage can be programmed from 0.8V to 5.5V. A submicron BiCMOS process delivers 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 ISL805xx 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.
