FUNCTION
Output Voltage Input. Connecting SET to ground selects the factory-preset 3.3V (MAX1658) or 5V
(MAX1659) output voltage. For an adjustable output voltage, connect SET to a resistive voltage divider from
OUT to GND.
Shutdown Input. When SHDN is low, the device turns off and typically draws 0.1μA of supply current.
Unregulated Input Supply Voltage, 2.7V to 16.5V input range. The IN pins also serve as heatsinks. Connect
to a copper plane to achieve maximum thermal dissipation.
Regulated Output Voltage. Fixed or adjustable from 1.25V to 16V. Sources up to 350mA. For stable opera-
tion, bypass with a 10μF, low-ESR (<0.2 ? ) capacitor from OUT to GND. For improved load-transient
response, use a larger low-ESR capacitor.
