Features and Benefits

Full featured evaluation boards for the ADP5037
Standalone capability
Simple device measurements, including line and load regulation, demonstrable with
- A single voltage supply
- A voltmeter
- An ammeter
- Load resistors
Easy access to external components
Cascading options to supply the low dropout (LDO) regulator from either buck regulator
