LD3980

Low drop - Low supply voltage

Low ESR capacitor compatible

Feature summary

■ Input voltage from 1.7 to 3.6V

■ Ultra low dropout voltage (130mV typ. at

300mA load)

■ Very low quiescent current (110µA typ. at no

load, 130µA max. at 300mA load; max 0.5µA in

OFF MODE)

■ Output voltage tolerance: +/- 1.0% @ 25°C, +/-

2.0% full temperature range

■ Guaranteed output current up to 300mA

■ Wide range of output voltage: 0.8V to 3.0V

■ Logic-controlled electronic shutdown

■ Compatible with ceramic capacitor CO = 1µF

■ Internal current and thermal limit

■ Temperature range: -40°C to 85°C

Description

The LD3980 provides up to 300mA, from 1.7V to

3.6V input voltage. It can deliver a guaranteed

300mA continuous load current with a low 100mV

dropout. It is stable with ceramic capacitor. The

ultra low drop-voltage, low quiescent current and

low noise makes it suitable for low power

applications and in battery powered systems.

High power supply rejection is maintained down

to low input voltage levels common to battery

operated circuits. Shutdown Logic Control

function is available this means that when the

device is used as local regulator, it is possible to

put a part of the board in standby, decreasing the

total power consumption. The device also

includes a constant current limiting and thermal

overload protection. Typical applications are in

mobile phone, personal digital assistant (PDAs),

cordless phone and similar battery powered

wireless systems, portable information

appliances..
