ISL8011xEVAL1Z Evaluation Board User Guide
Description
The ISL8011xEVAL1Z provides 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 V
provided a standard legacy 2.9V or 5.5V is applied on the
V
pin. The output voltage is adjustable from 0.8V to 3.3V.
