The MAX8516/MAX8517/MAX8518 low-dropout linear

regulators operate from input voltages as low as 1.425V

and are able to deliver up to 1A of continuous output

current with a maximum dropout voltage of only 200mV.

The output voltage can be set from 0.5V to (V

and is 1.4% accurate over load and line variations, from

0°C to +85°C.

These regulators use small, 1µF ceramic input capaci-

tors and 4.7µF ceramic output capacitors to deliver 1A

output current. High bandwidth provides excellent tran-

sient response and limits the output voltage deviation to

45mV for a 20mA to 1A load step, with only a 4.7µF

ceramic output capacitor, and the voltage deviations can

be reduced further by increasing the output capacitor.

Designed with an internal p-channel MOSFET pass

transistor, the MAX8516/MAX8517/MAX8518 feature

low 340µA (typ) supply current during dropout condi-

tions. Soft-start reduces inrush current. Other features

include a logic-controlled shutdown mode, short-circuit

protection, and thermal-overload protection.

The MAX8517 features a power-OK (POK) output that

transitions high when the regulator output is within

±10% of its nominal output voltage. The MAX8518

features a 150ms power-on reset output.

The parts are packaged in a 10-pin µMAX

includes an exposed pad for optimal power dissipation.
