? Ultra-small SC-70 package offers 40% smaller

footprint than SOT-23-3

? See TLVH431 and TLVH432 for:

– Wider VKA (1.24V to 18 V) and IK (80mA)

– Additional SOT-89 package

– Multiple pinouts for SOT-23-3 and SOT-89

packages

? On products compliant to MIL-PRF-38535, all

parameters are tested unless otherwise noted. on

all other products, production processing does not

necessarily include testing of all parameters.

2 Applications

? Adjustable voltage and current referencing

? Secondary side regulation in flyback SMPSs

? Zener replacement

? Voltage monitoring

? Comparator with integrated reference

3 Description

The TLV431 device is a low-voltage 3-terminal

adjustable voltage reference with specified thermal

stability over applicable industrial and commercial

temperature ranges. Output voltage can be set to

any value between VREF (1.24V) and 6V with two

external resistors (see the Parameter Measurement

Information section). These devices operate from a

lower voltage (1.24V) than the widely used TL431 and

TL1431 shunt-regulator references.

When used with an optocoupler, the TLV431 device is

an ideal voltage reference in isolated feedback circuits

for 3V to 3.3V switching-mode power supplies. These

devices have a typical output impedance of 0.25Ω.

Active output circuitry provides a very sharp turnon

characteristic, making them excellent replacements

for low-voltage Zener diodes in many applications,

including on-board regulation and adjustable power

supplies.
