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 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 micropower 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. TYPICAL APLICATION CIRCUIT

PIN DESCRIPTION
PIN NUMBER 1 2 3 4 5 PIN NAME VIN RO GND RD VOUT DESCRIPTION LDO Input. Bypass VIN to GND with a Ceramic capacitor. Reset Output. RO remains low while VOUT is below the reset switching threshold. RO is in open conector output. Ground. This pin also functions as a heatsink. Solder to large pads or the circuit-board ground plane to maximize thermal dissipation. Reset Delay. RD connects capacitor to GND for setting delay time. LDO Output. Bypass VOUT to GND with a minimum 22F capacitor with ESR less than 5 at 10kHz.
