STMicroelectronics Evaluation Board for LD39020 for LD39020 High PSRR

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.Output current: 200 mA Logic controlled electronic shutdown High PSRR 80 dB @ 1 kHz 50 db @ 100 kHz Quiescent current: 20 μA typ at no load 0.03 μA typ in off mode 1.8 V ± 0.5% output voltage DFN4-1 x 1 package
