General Description
The MAX4834/MAX4835 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
250mA of load current at a preset output voltage. Preset
output voltage levels are 1.8V/2.5V/2.8V/3.0V/3.3V.
The MAX4834/MAX4835 offer a programmable soft-
start control function to eliminate false reset during
startup. The MAX4834 provides a
FLAG
function to noti-
fy the system when the load current exceeds the limit.
The MAX4835 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 MAX4834/MAX4835 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 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, MAX4835EUT18BD2 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.
