250mA LDO Linear Regulators with

Current-Limiting Switch

General Description

The MAX4834/MAX4835 family of low-dropout (LDO)

linear regulators feature an accurate current-limiting

switch with an integrated

FLAG

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.
