LD2980Cxx

Ultra low drop voltage regulators compatible

with low ESR inhibit output capacitors

Features

■ Stable with low ESR ceramic capacitors

■ Ultra low dropout voltage (0.12 V typ. at 50 mA

load, 7 mV typ. at 1 mA load)

■ Very low quiescent current (80 µA typ. at no

load in on mode; max 1 µA in off mode)

■ Guaranteed output current up to 50 mA

■ Logic-controlled electronic shutdown

■ Output voltage of 1.8; 3.0; 3.3; 3.6; 5.0 V

■ Internal current and thermal limit

SOT23-5L

SOT-89

available on pin n° 3 (TTL compatible). 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 LD2980 is designed to work with low ESR

ceramic capacitors. Typical applications are

cellular phone, laptop computer, personal digital

assistant (PDA), personal stereo, camcorder and

camera.

■

0.5% Tolerance output voltage available (A

version)

■ Output low noise voltage 160 µVRMS

■ Temperature range: -40 to 125 °C

■ Smallest package SOT23-5L and SOT-89

■ Fast dynamic response to line and load

changes

Description

The low drop-voltage and the ultra low quiescent

current make them suitable for low noise, low

power applications and in battery

poweredsystems. The quiescent current in sleep

mode is less than 1 µA when the INHIBIT pin is

pulled low. A shutdown logic control function is

Table 1.
