500mA LDO Linear Regulators with
Current-Limiting Switch
General Description
The MAX4836/MAX4837 family of low-dropout (LDO)
linear regulators feature an accurate current-limiting
switch with an integrated FLAG or RESET 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 soft-
start control function to eliminate false reset during
startup. The MAX4836 provides a FLAG function to noti-
fy the system when the load current exceeds the limit.
The MAX4837 provides a RESET function to notify the
system when the output drops below the threshold.
Additionally, reverse-current protection prevents cur-
rent flowing from the output to the input. Other features
include a low 90μA quiescent current, a 0.1μA shut-
down current.
The MAX4836/MAX4837 are available in space-saving
6-pin SOT23 and TDFN packages. Each device is speci-
fied over the -40°C to +85°C extended temperature
range. Contact factory for other programmed output volt-
age 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

RESET and “C” for FLAG . “dd” is a placeholder for the reset
timeout period. Insert the values found in Table 2 in the place of
“dd.” For example, MAX4837EUT18BD2 has a 1.8V output volt-
age, RESET feature, and a 30ms reset timeout period. Note that
“dd” applies only to the devices with RESET option and does not
apply to the devices with FLAG option. For devices with the
