SPX29302AT5

The SPX29302AT5 is a kind of high accurate voltage regulator. It is packaged in 5-pin TO-263. The device is specifically designed for low voltage applications that require a low dropout voltage and a fast transient response. The typical applications include powering VGA & sound card, powerPC™ supplies, SMPS post regulator, high efficiency "Green" computer systems, high efficiency linear power supplies, constant current regulators, adjustable power supplies and battery charger.

There are some features of SPX29302AT5 . (1) adjustable output down to 1.25 V; (2) 1% output accuracy; (3) output current of 3 A; (4) low dropout voltage of 370 mV @ 3 A; (5) extremely fast transient response; (6) reverse-battery protection; (7) zero current shutdown (5 pin version).

What comes next is about the absolute maximum ratings of SPX29302AT5 . (1): input voltage is 16 V; (2): operating junction temperature is from -40 to +125; (3): storage temperature is from -65 to +150; (4): lead temperature (soldering, 5 seconds) is 260.

The following is about the electrical characteristics of SPX29302AT5 at VIN=VOUT+1 V and IOUT=10 mA, CIN=6.8µF, COUT = 10 µF, Tj=25, unless otherwise specified. The Boldface applies over the junction temperature range. (1): the typical ground pin current at dropout is 1.7 mA at VIN=0.5 V less than specified VOUT, IOUT=10 mA; (2): the typical current limit is 4.0 A and the maximum is 5.0 A at VOUT=0; (3): the typical reference voltage temp. coeff is 20 ppm/; (4): adjust pin bias current temp. coeff is 0.1 nA/.
