General Description
The APL1582 of high performance positive voltage regulators are designed for use in applications requiring very low dropout voltage at 3Amps . The APL1582 can provide a output voltage at the range of 1.25V to 2.55V , where both 5V and 3.3V voltage supplies are available . The superior dropout characteristics result in reduced heat dissipation compared to regular LDOs. The APL1582 also provides excellent regulation over line , load , and temperature variations. Current limit is trimmed to ensure specified output current and controlled short-circuit current . On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperature . The APL1582 is available in both the through-hole and surface mount versions of the industry standard 5-Pin TO-220, TO-252 and TO-263 power packages .

Pin Description
PIN Name VSENSE ADJ I/O I O Description Positive side of the reference voltage, which allows remote sensing to obtain excellent load regulation. Negative side of the reference voltage, which allows to use resistor divider to set an expect output voltage. A small bypass capacitor can be connected from this pin to ground to improve PSRR performance. Output pin of the regulator, which connects to the TAB. A minimum of 10F capacitor must be connected from this pin to ground to ensure the stability. Supply pin of the control circuitry, which must be always higher than VOUT for the device to regulate. (see electrical characteristics) Power input pin of the regulator, which must be always higher than VOUT for the device to regulate. (see electrical characteristics)
