APL1085 3A Low Dropout Fast Response Positive Adjustable Regulator and Fixed 3.3V Features General Description • • The APL1085 is a low dropout three-terminal adjustable regulator with 3A output current capability. In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications, the APL1085 has been optimized. The output available voltage range of adjustable version is from 1.25~5.75V with an input supply below 7V , and the fixed 3.3V output voltage device is also available. Fast Transient Response Guaranteed Dropout Voltage at Multiple Currents • • • • • • Load Regulation : 0.05% Typ. Line Regulation : 0.03% Typ. Low Dropout Voltage : 1.2V Typ. at IOUT =3A Trimmed Current Limit : 3A Typ. at TJ=125 °C 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 temperatures. On-Chip Thermal Limiting : 150 °C Typ. Standard 3-pin TO-220 , TO-252 and TO-263 Power Package The APL1085 is available in both the through-hole and surface mount versions of the industry standard Applications • • • • • Pin Description PentiumTM Processor Supplies PowerPC TM Supplies Low Voltage Logic Supplies TAB is VOUT Battery-Powered Circuitry Post Regulator for Switching Power Supply 3 VIN 2 VOUT 1 ADJ Front View APL1085 TO-220 Package TA B is V OU T 3 V IN 2 V OUT 1 AD J Front View APL1085 TO-252 Package TA B is V OU T 3 V IN 2 V OUT 1 AD J Front View APL1085 TO-263 Package ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders.
