ADM663A

GENERAL DESCRIPTION

GND

The ADM663A/ADM666A are precision linear voltage regula-

tors featuring a maximum quiescent current of 9 µA. They can

be used to give a fixed +3.3 V or +5 V output with no additional

external components or can be adjusted from 1.3 V to 16 V

using two external resistors. Fixed or adjustable operation is au-

tomatically selected via the V_SETinput. The low quiescent cur-

rent makes these devices especially suitable for battery powered

systems. The input voltage range is 2 V to 16.5 V, and an out-

put current up to 100 mA is provided. Current limiting may be

set using a single external resistor. For additional safety, an

internal thermal shutdown circuit monitors the internal die

temperature.

The ADM663A/ADM666A are pin compatible enhancements

for the ADM663/ADM666. Improvements include an addi-

tional 3.3 V output range, higher output current, and operation

with a small output capacitor.

The ADM663A/ADM666A are available in an 8-pin DIP and

narrow surface mount (SOIC) packages.
