Bare Die Product Detail: SiS1084L-3.3

Regulator output > 300mA:
SiS1084L-3.3 is a fixed 3.3 Volt 5A positive low dropout regulator includes zener trimmed bandgap reference, current limiting & thermal shutdown. Output voltage is set using two external resistors. Dropout voltage of 1.5V is guaranteed at 5A load.
This bare die suits hybrid & MCM designs needing high output current, fixed 3.3V regulation & smallest size. Other than lower input voltage range, the part is functionally equivalent to the industry LM1084 or LT1084 with ~40% footprint reduction.
Features:
