The ISL80505 is a single output Low Dropout voltage regulator (LDO) capable of sourcing up to 500mA output current. This LDO operates from input voltages of 1. 8V to 6V. The output voltage of ISL80505 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 ISL80505 provides an output accuracy of ±1. 8% VOUT accuracy over all load, line and temperature variations (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.
