Ultra Low Dropout 1A Low Input Voltage NMOS LDOs Evaluation Boards


The ISL8011xEVAL1Z family of boards (ISL80111EVAL1Z, ISL80112EVAL1Z, ISL80113EVAL1Z) provide a simple platform to evaluate performance of the ISL8011x family of split supply LDOs. Jumpers are provided to easily set popular output voltages.

The ISL80111, ISL80112 and ISL80113 are single-output LDOs specified for 1A, 2A, 3A of output current and are optimized for less than 2.5V and less output voltage conversions. The ISL8011x supports VIN voltages down to 1V, provided a standard legacy 2.9V or 5.5V is applied on the VBIAS pin. The output voltage is adjustable from 0.8V to 3.3V.
