FEATURES  
DESCRIPTION  
The LT®3070 is a low voltage, UltraFast™ transient re-  
sponse linear regulator. The device supplies up to 5A of  
output current with a typical dropout voltage of 85mV.

permits the use of low ESR ceramic capacitors, saving  
bulk capacitance and cost. The LT3070’s features make  
it ideal for high performance FPGAs, microprocessors or

Output voltage is digitally selectable in 50mV increments  
over a 0.8V to 1.8V range. A margining function allows  
the user to adjust system output voltage in increments of  
1ꢀ, 3ꢀ or 5ꢀ. The IC incorporates a uniꢁue tracking
