STEVAL-ISB037V1:Evaluation board for the LD39020 High PSRR, 200mA LDO

The STEVAL-ISB037V1 board features the LD39020 high performance linear voltage regulator, configured to convert a DC input voltage from 2.4 V to 5.5 V into a precise and stable 1.8 V 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.
