Anpec Electronics APL431L
The APL431L is a 3-terminal low voltage adjustable precision reference with specified thermal stability over applicable commercial temperature ranges. 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.FEATURES
GENERAL DESCRIPTION
● 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

APPLICATIONS
● Linear Regulators● Adjustable Power Supply
● Switching Power Supply Output voltage may be set to any value between VREF (1.24 V) and 20 V with two external resistors (see Figure 2). 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.
