APL1431L

Low Voltage Adjustable Precision Shunt Regulator

Features General Description

• Precise Reference Voltage to 1.24V

• Guaranteed 0.5% or 1% Reference Voltage

Tolerance

• Sink Current Capability , 60mA to 100mA

• Quick Turn-on

• Adjustable Output Voltage , V

REF

to 20V

• Low Operational Cathode Current , 60mA

Typical

• 0.1Ω Typical Output Impedance

• SOT-23-5 Packages

Applications

•

Linear Regulators

• Adjustable Power Supply

• Switching Power Supply

The APL1431L is a 3-terminal low voltage adjust-

able precision reference with specified thermal sta-

bility over applicable commercial temperature ranges

. Output voltage may be set to any value between

V

(1.24 V) and 20 V with two external resistors

REF

(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 .
