Out-put voltage may be set to any value between V ref (1.24 V) and 20 V with two external resistors (see Fig-ure 2). When used with an photocoupler, the APL431L is an ideal voltage reference in isolated feed-back circuits for 3V to 12V switching-mode power supplies. This device has a typical output imped-ance of 0.1Ω. Active output circuitry provides a very sharp turn-on characteristic, making the APL431L ex-cellent replacements for zener diodes in many applications, including on-board regulation and ad-justable power supplies.• Precise Reference Voltage to 1.24V• Guaranteed 0.5% or 1% Reference VoltageTolerance• Sink Current Capability, 80uA to 100mA • Quick Turn-on• Adjustable Output Voltage, V O = V REF to 20V • Low Operational Cathode Current, 80µATypical• 0.1Ω Typical Output Impedance• SOT-23-3, SOT-23-5, TO-92 and SOT-89Packages• Lead Free Available (RoHS Compliant)• Linear Regulators• Adjustable Power Supply • Switching Power SupplySymbolFunctional DiagramSOT-23-3 (Top View)REF ANODECATHODE123SOT-89 (Top View)REFANODE CATHODE123REFANODECATHO DE321TO-92 (Top View)CathodeAnodeREFREF NCCATHODENCANODE 12345SOT-23-5 (Top View)APL431LOrdering and Marking InformationNotes： ANPEC lead-free products contain molding compounds/die attach materials and 100% matte in plate termination finish; which are fully compliant with RoHS and compatible with both SnPb and lead-free soldiering operations.
