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 V

(1.

ref

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.

1)To improve the stability of output voltage, a 0.1µF capacitor between cathode and anode of APL431L is
strongly recommended.

2)Set VOUT according to the following equation:
VOUT = VREF(1+R1/R2)+lREF R1

3)Choose the value for RB as follows:
A)The maximum limit for RB should be such that the cathode current(lK) is greater than the minimum op­ erating current (80µA) at VIN(MIN).
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 turn-on value for lk does not exceed 150mA. Both of the fo­ llowing conditions must. be met:
VIN(MAX)

RB,Min≥

150mA

VIN(MAX)-VOUT

RB,Min≥

lOUT(MIN)+100mA

(to limit instantaneous turn-on lK)

(to limit lK under normal operating conditions)
