Wide Input Linear Voltage Regulator, 3991.31.1, Diotec

This board is used to demonstrate the functionality of the LDI55-ADEEN linear regulator. It has wide input range up to 50V, low-dropout (LDO) voltage regulators with enable function and provides up to 1A of output current. Only two small ceramic capacitors are needed to implement the linear regulator solution. The features of low quiescent current as low as 3 µA to 5 µA and almost 0.5 µA disable current is ideal for powering the battery equipment to a longer service. Simple device measurements such as line and load regulation, dropout, can be demonstrated with just a single voltage source, a voltmeter, an ammeter, and load resistor.
