Anpec APL1582FC-TU Dual input low dropout regulator Datasheet

APL1582
DUAL INPUT LOW DROPOUT REGULATOR
Features
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 .

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
10µF 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)
