LT3029  
Dual 500mA/500mA  
Low Dropout, Low Noise,  
Micropower Linear Regulator  
DESCRIPTION  
FEATURES  
The LT®3029 is a dual, micropower, low noise, low drop-  
out linear regulator. The device operates either with a  
common input supply or independent input supplies for  
each channel, over an input voltage range of 1.8V to 20V.  
Each output supplies up to 500mA of output current with  
a typical dropout voltage of 300mV. Quiescent current is  
well controlled in dropout. With an external 10nF bypass

100kHz bandwidth. Designed for use in battery-powered  
systems,thelow55μAquiescentcurrentperchannelmakes  
it an ideal choice. In shutdown, quiescent current drops to  
less than 1μA. Shutdown control is independent for each  
channel, allowing for flexible power management.

Internal circuitry provides reverse-battery protection,  
reverse-current protection, current limiting with foldback  
and thermal shutdown. The device is available as an  
adjustable output voltage device with a 1.215V reference

16-lead MSOP and 16-lead, low profile (4mm × 3mm ×  
0.75mm) DFN packages.
