The MAX4836/MAX4837 family of low-dropout linear
regulators (LDOs) feature an accurate current-limiting
switch with an integrated FLAG-bar or RESET-bar function. These
devices operate from 2.5V to 5.5V and deliver up to
500mA of load current at a preset output voltage. Preset
output voltage levels are 1.8V/2.5V/2.8V/3.0V/3.3V.
The MAX4836/MAX4837 offer a programmable softstart
control function to eliminate false reset during
startup. The MAX4836 provides a FLAG-bar function to notify
the system when the load current exceeds the limit.
The MAX4837 provides a RESET-bar function to notify the
system when the output drops below the threshold.
Additionally, reverse-current protection prevents current
flowing from the output to the input. Other features
include a low 90µA quiescent current, a 0.1µA shutdown
current.
The MAX4836/MAX4837 are available in space-saving
6-pin SOT23 and TDFN packages. Each device is specified
over the -40°C to +85°C extended temperature
range. Contact factory for other programmed output voltage
versions from 1.5V to 3.3V in 100mV increments.
For pin-compatible 100mA versions of this device, refer
to the MAX4832/MAX4833. For pin-compatible 250mA
versions of this device, refer to the MAX4834/MAX4835.
