Evaluation Board For High Performance 1A LDO

The ISL80101 is a low voltage, high current, single output LDO specified at 1A output current. This LDO operates from input voltages of 2.2V to 6V. Fixed output voltage options are available in 1.8V, 2.5V, 3.3V and 5.0V versions. Other custom voltage options are available upon request. For the adjustable output version of the ISL80101. 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. 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.
