General Description
The MAX8633–MAX8636 offer low-dropout (LDO) volt-
age and ultra-low-power regulation in a subminiaturized
2mm x 2mm μDFN package. The devices operate from
a 2.7V to 5.5V supply and deliver up to 300mA from
each output, with a typical dropout voltage of 90mV at
100mA load current. Each device is designed with
internal p-channel MOSFET pass transistors to ensure a
low-quiescent supply current of 54μA (typical, both
LDOs on). Other features include low-noise operation
(MAX8634/MAX8636), output current limiting, and ther-
mal shutdown.
The MAX8633 features an open-drain, active-low
RESET output to monitor OUT2, eliminating external
components and adjustments. The MAX8633 asserts a
RESET signal (120ms minimum timeout) when VOUT2
drops below 87% of the nominal output voltage. The

Ordering Information
MAX8634/MAX8636 feature a noise bypass input to the
internal reference for low output noise (45μV RMS typ).

inputs for disabling the regulators, while the MAX8633/
MAX8636 provide a single SHDN input for disabling
both regulators.
The MAX8633/MAX8635/MAX8636 have two logic
inputs that select one of nine preset output-voltage
combinations, eliminating external 1% resistors, as well
as inventory burden. The MAX8634 has one logic input

8-pin, 3mm x 3mm TDFN package for higher power dis-
sipation. The devices are specified over the extended
