The ISL80101-ADJ is a low voltage, high current, single output LDO specified at 1A output current. This LDO operates from input voltages from 2. 2V to 6V, and is capable of providing output voltages from 0. 8V to 5V. The ISL80101-ADJ features an adjustable output. For the fixed output version of the ISL80101-ADJ, please refer to the ISL80101 datasheet. A submicron BiCMOS process is utilized for this product family to deliver the best in class analog performance and overall value. This CMOS LDO will consume 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. 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. A Power-good logic output signals a fault condition.
