General Description
The MAX4832/MAX4833 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
100mA of load current at a preset output voltage. Preset
output voltage levels are 1.8V/2.5V/2.8V/3.0V/3.3V.
The MAX4832/MAX4833 offer a programmable soft-
start control function to eliminate false reset during
startup. The MAX4832 provides a FLAG function to noti-
fy the system when the load current exceeds the limit.
The MAX4833 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 90A quiescent current, a 0.1A shut-
down current.
The MAX4832/MAX4833 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 250mA versions of this device, refer
to the MAX4834/MAX4835. For pin-compatible 500mA
versions of this device, refer to the MAX4836/MAX4837.

Note: “xy” are placeholders for the output voltage levels of the
devices. Insert the values found in Table 1 at the end of this doc-
ument in the place of “xy”. The “_” is a placeholder for either the
RESET or the FLAG feature. Insert “B” in the place of “_” for
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, MAX4833EUT18BD2 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
FLAG option, leave dd blank. Standard versions require a mini-
mum order increment of 2.5k units. Nonstandard versions must
be ordered in 10k unit increments. Contact factory for availability.
