STEVAL-ISB037V1

The STEVAL-ISB037V1 is an evaluation board for the LD39020 high PSRR, 200mA low dropout voltage regulator. The STEVAL-ISB037V1 board features the LD39020 high performance linear voltage regulator, configured to convert a DC input voltage from 2.4V to 5.5V into a precise and stable 1.8V output voltage. Only two small ceramic capacitors are needed to implement the linear regulator solution. The very low dropout LD39020 voltage regulator features high PSRR and low quiescent current in a tiny DFN4 package with a footprint of only (1 x 1)mm². It is designed for low-power battery operated equipment such as smartphones, tablets and wearable devices.
