Adjustable Output Voltage LDO Regulator Evaluation Board

Overview

The demoboard supports the LDO regulator NCP3337 in DFN10 package with adjustable output voltage. The ENABLE function allows turn the device to low consumption mode with quiescent current below 1 µA. The Power Good pin alows output voltage monitoring. The additional CNR capacitor reduces the output noise.

Size: 45mm x 30mm x 18mm
