APL431L Low Voltage Adjustable Precision Shunt Regulator
• Precise Reference Voltage to 1.24V • Guaranteed 0.5%, 1% or 1.5% Reference Voltage Tolerance • Sink Current Capability, 80uA to 100mA • Quick Turn-on • Adjustable Output Voltage, VO = VREF to 20V • Low Operational Cathode Current, 80µA Typical • 0.1Ω Typical Output Impedance • SOT-23-3, SOT-23-5, TO-92 and SOT-89 Packages • Lead Free and Green Devices Available (RoHS Compliant) Applications • Linear Regulators • Adjustable Power Supply • Switching Power Supply The APL431L is a 3-terminal low voltage adjustable precision reference with specified thermal stability over applicable commercial temperature ranges. Output voltage may be set to any value between VREF (1.24 V) and 20 V with two external resistors (see Figure 2). When used with an photocoupler, the APL431L is an ideal voltage reference in isolated feedback circuits for 3V to 12V switching-mode power supplies. This device has a typical output impedance of 0.1W. Active output circuitry provides a very sharp turn-on characteristic, making the APL431L excellent replacements for zener diodes in many applications, including on-board regulation and adjustable power supplies.
