LD39100XX  
LD39100XX12, LD39100XX25  
1 A, low quiescent current, low noise voltage regulator  
Preliminary data  
Features  
■ Input voltage from 1.5 to 5.5 V  
■ Ultra low dropout voltage (200 mV typ. at 1 A  
load)  
■ Very low quiescent current (20 µA typ. at no  
load, 200 µA typ. at 1 A load, 1 µA max in off  
mode)  
■ Very low noise with no bypass capacitor  
DFN6 (3 x 3 mm)  
(30 µV  
at V  
= 0.8 V)  
RMS  
OUT  
■ Output voltage tolerance: 2.0 % @ 25 °C  
■ 1 A guaranteed output current  
An enable logic control function puts the  
LD39100xx in shutdown mode, allowing a total  
current consumption lower than 1 µA. The device  
also includes short-circuit constant current limiting  
and thermal protection. Typical applications are  
printers, personal digital assistants (PDAs),  
cordless phones and consumer applications.  
■ Wide range of output voltages available on  
request: 0.8 V to 4.5 V with 100 mV step and  
adjustable from 0.8 V  
■ Logic-controlled electronic shutdown  
■ Stabilized with ceramic capacitors C  
■ Internal current and thermal limit  
■ DFN6 (3 x 3 mm) package  
= 1 µF  
OUT  
■ Temperature range: - 40 °C to 125 °C  
Description  
The LD39100xx provides 1 A maximum current  
from an input voltage ranging from 1.5 V to 5.5 V  
with a typical dropout voltage of 200 mV. The  
deveice is stable due to the use of ceramic  
capacitors on the input and output. The ultra low  
drop-voltage, low quiescent current and low noise  
features make it suitable for low power battery  
powered applications. Power supply rejection is  
65 dB at low frequencies and starts to roll off at 10  
kHz.
