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
automotive battery voltage, with allowable input up to 45V, down to 5V with at least 400mA output
current delivered. Internal power consumption is kept to 60uA ideal for applications where micro-
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.
