The MAX8526/MAX8527/MAX8528 low-dropout linear

regulators operate from input voltages as low as 1.425V

and are able to deliver up to 2A 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, 2.2µF ceramic input capaci-

tors and 10µF ceramic output capacitors to deliver 2A

output current. High bandwidth provides excellent tran-

sient response and limits the output voltage deviation to

45mV for a 20mA to 2A load step, with only a 10µF

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 MAX8526/MAX8527/MAX8528 feature

low 500µA typical 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 MAX8527 features a power-OK (POK) output that

transitions high when the regulator output is within

±10% of its nominal output voltage. The MAX8528 fea-

tures a 150ms power-on reset (POR) output.

The parts are packaged in a 14-pin TSSOP package,

which includes an exposed pad for optimal power

dissipation.
