APL1431L
Low Voltage Adjustable Precision Shunt Regulator
Features
General Description
The APL1431L is a 3-terminal low voltage adjust-
•
•
Precise Reference Voltage to 1.24V
able precision reference with specified thermal sta-
bility 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 iso-
lated feedback circuits for 1.24V 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 , mak-
ing the APL1431L excellent replacements for zener
diodes in many applications , including on-board
regulation and adjustable power supplies .

Notes for Application Circuits:
1) To improve the stability of output voltage , a 0.1µF capacitor between cathode and anode of APL431L
is strongly recommended.
2) Set VO according to the following equation:
VO= VREF (1+R1/ R2)+ IREF R1
3) 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 :
R
R
B,MIN ≥ VIN(MAX) / 150mA ( to limit instantaneous turn-on IK)
B,MIN ≥ VIN(MAX) - VO / IO (MIN) + 100mA (to limit IK under normal operating conditions)
