ISL80505 - High Performance 500mA LDO
PIN NUMBER 1, 2 3 4 5 6 7, 8 - PIN NAME VOUT FB GND ENABLE SS VIN EPAD DESCRIPTION Regulated output voltage. A minimum 4.7µF X5R/X7R output capacitor is required for stability. See “External Capacitor Requirements” on page 10 for more details. This pin is the input to the control loop error ampl.
ISL80505 High Performance 500mA LDO 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 .
