LD3985xx  
Ultra low drop-low noise BiCMOS voltage  
regulators low ESR capacitors compatible  
Features  
■ Input voltage from 2.5 V to 6 V  
■ Stable with low ESR ceramic capacitors  
■ Ultra low dropout voltage (100 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)  
Flip-chip  
(1.57x1.22)  
SOT23-5L  
TSOT23-5L  
■ Guaranteed output current up to 150 mA  
■ Wide range of output voltage: 1.22 V; 1.8 V;  
2.5 V; 2.6 V; 2.7 V; 2.8 V; 2.9 V; 3 V; 3.3 V;  
4.7 V  
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 only slightly  
in dropout, further prolonging the battery life.  
Power supply rejection is better than 60 dB at low  
frequencies and starts to roll 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 LD3985xx is designed to work  
with low ESR ceramic capacitors. Typical  
■ Fast turn-on time: typ. 200 µs  
[C = 1 µF, C  
= 10 nF and I = 1 mA]

■ Logic-controlled electronic shutdown  
■ Internal current and thermal limit  
■ Output low noise voltage 30 µV  
over 10 Hz  
RMS  
to 100 kHz  
■ S.V.R. of 60 dB at 1 kHz, 50 dB at 10 kHz  
■ Temperature range: -40 °C to 125 °C  
Description  
applications are in mobile phone and similar  
battery powered wireless systems.  
The LD3985xx provides up to 150 mA, from 2.5 V  
to 6 V input voltage.
