MAX1819 Evaluation Kit

General Description

The MAX1819 linear regulator evaluation kit (EV kit) pro-

vides a regulated 1.8V output voltage from a 2.5V to 5.5V

input source. It delivers up to 500mA output current.

Features

ꢀ 2.5V to 5.5V Input Voltage Range

ꢀ Up to 500mA Output Current

ꢀ Output Voltage

The EV kit is a fully assembled and tested surface-mount

PC board. It can also evaluate other output voltages in

the 1.25V to 5.0V range by using external resistors.

Quick Start

The MAX1819 EV kit is fully assembled and tested.

Follow these steps to verify board operation.

JU1

3-pin header

Not installed (0603)

Not installed, pads shorted with PC

trace (0603)

Do not turn on the power supply until all connec-

tions are completed:

100kΩ 5% resistor (0603)

1) Verify that the shunt is across pins 1 and 2 of

jumper JU1 (SHDN) (Table 1).

2) Connect a voltmeter to the VOUT pad. Connect the

ground to the GND pad closest to VOUT.

3) Connect a 2.5V to 5.5V supply to the VIN pad.

Connect the supply ground to the GND pad closest

to VIN.

4) Turn on the power supply and verify that the output

is the preset voltage of 1.8V.

To evaluate other voltages, see the Evaluating Other

Output Voltages section.
