DATASHEET ISL80121-5 1A Ultra Low Dropout Linear Regulator with Programmable Current Limiting FN7713 Rev 6.00 March 21, 2016 The ISL80121-5 is a low dropout voltage, single output LDO with programmable current limiting. The ISL80121-5 operates from input voltages of 5V to 6V with a nominal output voltage of 5V. Other custom voltage options are available upon request. A submicron BiCMOS process is utilized for this product family to deliver the best in class analog performance and overall value. The programmable current limiting improves system reliability of end applications. An external capacitor on the soft-start pin provides an adjustable soft-starting ramp. The ENABLE feature allows the part to be placed into a low quiescent current shutdown mode.
