LDS3985xx  
Ultra low drop-low noise BiCMOS 300 mA voltage  
regulator for use with very low ESR output capacitor  
Features  
Input voltage from 2.5 V to 6 V  
Stable with low ESR ceramic capacitors  
Ultra low dropout voltage (150 mV typ. at 300  
mA load, 0.4 mV typ. at 1 mA load)  
Very low quiescent current (85 µA typ. at no  
load, 200 µA typ. at 300 mA load; max 1.5 µA  
in off mode)  
DFN6  
SOT23-5L  
Guaranteed output current up to 300 mA  
Wide range of output voltage:  
– from 1.25 V to 5.0 V  
Fast turn-on time: typ. 240 µs  
makes it suitable for low power applications and in  
battery powered systems. Regulator ground  
current increases only slightly in dropout, further  
prolonging the battery life. 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. Typical applications are  
in mobile phone and similar battery powered  
wireless systems, portable information

Description  
The LDS3985xx provides up to 300 mA, from 2.5  
V to 6 V input voltage. It is stable with ceramic and
