Enable Input. Set low to place the device in low-current shutdown mode. Set
high for normal operation.
Regulator Input. V
higher ceramic capacitor to GND.
Test Pin
Ground
Feedback Pin. Connect to output through a voltage-divider to set the output.
Regulator Output. Bypass with a 10µF ceramic capacitor to GND (a smaller
capacitor can be used if maximum load is less than 2A, i.e., C
x (1µF/200mA).
Power-OK Output (MAX8527 Only). Open-drain output. Connect to a positive
supply with a pullup resistor. If not used, leave pin unconnected. See the
Detailed Description for more details.
Power-On Reset Output. Open-drain output. Connect to a positive supply with
a pullup resistor. If not used, leave pin unconnected. See the Detailed
Description for more details.
Exposed Pad on the Underside of the Package. Solder to the ground plane for
proper heat dissipation.
