T he ADM663/ADM666 are precision voltage regulators featur-
ing a maximum quiescent current of 12
μ
A. T hey can be used to
give a fixed +5 V output with no additional external compo-
nents or can be adjusted from 1.3 V to 16 V using two external
resistors. Fixed or adjustable operation is automatically selected
via the V
SET
input. T he low quiescent current makes these de-
vices especially suitable for battery powered systems. T he input
voltage range is 2 V to 16.5 V and an output current up to
40 mA is provided. T he ADM663 can directly drive an external
pass transistor for currents in excess of 40 mA. Additional fea-
tures include current limiting and low power shutdown. T her-
mal shutdown circuitry is also included for additional safety.
T he ADM666 features additional low battery monitoring
circuitry to detect for low battery voltages.
T he ADM663/ADM666 are pin-compatible replacements for
the MAX 663/666. Both are available in 8-pin DIP and in nar-
row surface mount (SOIC) packages.
