100mA LDO Linear Regulators with

Current-Limiting Switch

General Description

Features

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.

♦ Guaranteed Minimum 100mA Load Current

♦ Accurate Current Limit

♦ Preset Output Voltages: 1.8V/2.5V/2.8V/3.0V/3.3V

♦ 2.5V to 5.5V Supply Voltage Range

♦ Adjustable Soft-Start

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 90µA quiescent current, a 0.1µA shut-

down current.

♦ Low Dropout Voltage

♦ Thermal Shutdown

♦ Reverse-Current Protection

♦ Shutdown Output Discharge (MAX4833)

♦ Low 90µA Supply Current

♦ Ultra-Low 0.1µA Shutdown 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.

♦ FLAG and Latch Off (MAX4832) or RESET

(MAX4833)

♦ Tiny SOT23 and TDFN Packages

Ordering Information

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.
