DESCRIPTION

Sipex’s SPX2975 is a low dropout linear regulator with integrated PNP pass transistor. The part

is available in a 5 pin TO-220 package or surface mount TO-263. The part used to convert an

automotivebatteryvoltage,withallowableinputupto45V,downto5Vwithatleast400mAoutput

currentdelivered. Internalpowerconsumptioniskeptto60uAidealforapplicationswheremicro-

power operation is important. At over-temperature the SPX2975 is turned off by the integrated

temperature protection circuit. A reset signal is generated for a typical output voltage of 4.65V

with a time delay that can be programmed by an external delay capacitor.
