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.

LDO Input. Bypass VIN to GND with a Ceramic capacitor.
RO
Reset Output. RO remains low while VOUT is below the reset switching
threshold. RO is in open conector output.
3
GND
Ground. This pin also functions as a heatsink. Solder to large pads or the
circuit-board ground plane to maximize thermal dissipation.

5
RD
Reset Delay. RD connects capacitor to GND for setting delay time.
VOUT
LDO Output. Bypass VOUT to GND with a minimum 22µF capacitor with
ESR less than 5Ω at 10kHz.
