STMICROELECTRONICS STEVALISB037V1 Linear Voltage Regulator

The STEVAL-ISB037V1 evaluation board features the LD39020 high PSRR, 200 mA linear voltage regulator, designed for low-power battery-powered devices such as smartphones, tablets, and wearable devices. It converts input DC voltage from 2.4 V to 5.5 V into a precise 1.8 V output with high PSRR and low quiescent current. The regulator requires only two small ceramic capacitors, is housed in a tiny DFN4 package measuring 1 x 1 mm, and supports logic-controlled shutdown. Variations of output voltage are available upon request, and the device is RoHS compliant.
