1.425V to 3.6V Input, 500mA Low-Dropout

Regulators with BIAS Input

29/MAX1530

General Description

Features

The MAX15029/MAX15030 low-dropout linear regula-

tors operate from input voltages as low as 1.425V and

deliver up to 500mA of continuous output current with a

typical dropout voltage of only 40mV. The output volt-

♦ 1.425V to 3.6V Input Voltage Range

♦ Output Voltage Programmable from 0.5V to V

♦ Guaranteed Maximum 150mV Dropout for

Standard Package and 190mV Dropout for Side-

Wettable Package at 500mA Output Current

age is adjustable from 0.5V to V and is 2ꢀ accurate

over load and line variations, from -40°C to +125°C.

The MAX15030 features a BIAS input of 3V to 5.5V from

an always-on power supply. The BIAS input current is

reduced down to less than 2µA during the shutdown.

♦ 2% Output Accuracy Over Load, Line, and Temperature

♦ Stable with Ceramic Capacitors

♦ Fast Transient Response

These regulators use small, 1µF ceramic input capaci-

tors and 2.2µF ceramic output capacitors to deliver

500mA output current. High bandwidth provides excel-

lent transient response and limits the output voltage devi-

ation to 10mV for a 100mA to 500mA load step, with only

a 2.2µF ceramic output capacitor, and the voltage devia-

tions can be reduced further by increasing the output

capacitor.

♦ 60µA Operating Bias Supply Current

♦ 1.2µA Shutdown Bias Supply Current

♦ Short-Circuit and Thermal Protection

♦ -40°C to +125°C Operating Temperature Range

♦ Soft-Start Limits Inrush Current

♦ Thermally Enhanced 3mm x 3mm TDFN Package

These devices offer a logic-controlled shutdown input

to reduce input current (I ) consumption down to less

than 5.5µA in standby mode. Other features include a

soft-start to reduce inrush current, short-circuit protec-

tion, and thermal-overload protection.

The MAX15030 features a BIAS input allowing a sec-

ondary supply to keep the LDO’s internal circuitry alive

if the voltage on IN goes to 0. Both devices are fully

specified from -40°C to +125°C and are available in a

10-pin thermally enhanced TDFN package (3mm x

3mm) that includes an exposed pad for optimal power

dissipation. For a 1A version of these LDOs, refer to the

MAX15027/MAX15028 data sheet.
