APL1431L
Low Voltage Adjustable Precision Shunt Regulator
Features
General Description
•
•
The APL1431L 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 APL1431L is an ideal voltage reference in isolated feedback circuits for 1.24V to 12V switchingmode power supplies . This device has a typical
output impedance of 0.1Ω . Active output circuitry
provides a very sharp turn-on characteristic , making the APL1431L excellent replacements for zener
diodes in many applications , including on-board
regulation and adjustable power supplies .

To improve the stability of output voltage , a 0.1µF capacitor between cathode and anode of APL431L
is strongly recommended.
Set VO according to the following equation:
VO= VREF (1+R1/ R2)+ IREF R1
Choose the value for RB as follows:
The maximum limit for RB should be such that the cathode current( IK) is greater than the minimum
operating current (60µA) at VIN (MIN) .
The minimum limit for RB should be such that the cathode current (IK) does not exceed 100mA under
all load conditions, and the instantaneous turn-on value for IK does not exceed 150mA . Both of the
following conditions must be met :
RB,MIN ≥ VIN(MAX) / 150mA ( to limit instantaneous turn-on IK)
RB,MIN ≥ VIN(MAX) - VO / IO (MIN) + 100mA (to limit IK under normal operating conditions)
