LD3985

Ultra low drop and low noise BiCMOS voltage regulators

Datasheet

production data

Features

•

Input voltage from 2.5 V to 6 V

•

Stable with low ESR ceramic capacitors

•

Ultra low-dropout voltage (60 mV typ. at 150

mA load, 0.4 mV typ. at 1 mA load)

•

Very low quiescent current (85 µA typ. at no

load, 170 µA typ. at 150 mA load; max.1.5 µA

in OFF mode)

•

Guaranteed output current up to 150 mA

•

Wide range of output voltages: 1.22 V; 1.8 V;

2.5 V; 2.7 V; 2.8 V; 2.9 V; 3 V; 3.3 V; 4.7 V

•

Fast turn-on time: typ. 200 µs [C

= 1 µF,

BYP

= 10 nF and I

= 1 mA]

•

Logic-controlled electronic shutdown

•

Internal current and thermal limit

•

Output low noise voltage 30 µV

RMS

over 10 Hz

to 100 kHz

•

SVR of 60 dB at 1 kHz, 50 dB at 10 kHz

•

Temperature range: - 40 °C to 125 °C

Power supply rejection is better than 60 dB at low

frequencies and rolls off at 10 kHz. 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 LD3985 is designed to

work with low ESR ceramic capacitors. Typical

applications are in mobile phones and similar

battery-powered wireless systems.

Description

The LD3985 provides up to 150 mA, from 2.5 V to

6 V input voltage. The ultra low drop voltage, low

quiescent current and low noise make it suitable

for low power applications and in battery-powered

systems. Regulator ground current increases

slightly in dropout only, prolonging the battery life.
