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. 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.
