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 0.1Ω. 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.

B)The minimum limit for RB should be such that the cathode current (lK) does not exceed 100mA under all load conditions, and the instantaneous turnon value for lk does not exceed 150mA. Both of the following conditions must. be met: VIN(MAX) RB,Min≥ 150mA (to limit instantaneous turn-on lK) RB,Min≥ VIN(MAX)-VOUT lOUT(MIN)+100mA (to limit lK under normal operating conditions) Copyright  ANPEC Electronics Corp.
