TLVH431B-EP

SLVSFF4 –DECEMBER 2019

TLVH431B-EP Enhanced Plastic 0.5% Low-Voltage Wide-Operating Current

Adjustable Precision Shunt Regulator

1 Features

3 Description

The TLVH431B-EP device is

a low-voltage, 3-

•

Low-voltage operation: down to 1.24 V

Reference voltage tolerances 0.5% at 25°C

Adjustable output voltage, V_O= V_REFto 18 V

terminal, adjustable voltage reference with specified

thermal stability over applicable industrial and

commercial temperature ranges. Output voltage can

be set to any value between V_REF(1.24 V) and 18 V

with two external resistors (see Figure 24). This

device operates from a lower voltage (1.24 V) than

the widely used TL431 and TL1431 shunt-regulator

references.

•

Wide operating cathode current range:

200 μA to 70 mA

•

0.25-Ω typical output impedance

Supports defense and aerospace applications:

–

Controlled baseline

When used with an optocoupler, the TLVH431B-EP

device is ideal for voltage references in isolated

feedback circuits designed for 3-V to 3.3-V switching-

Available in extended (–55°C to 125°C)

temperature range

mode power supplies. It has

a typical output

impedance of 0.25 Ω. Active output circuitry provides

a very sharp turn-on characteristic, making the

TLVH431B-EP device an excellent replacement for

low-voltage Zener diodes in many applications,

including on-board regulation and adjustable power

supplies.

2 Applications

•

Adjustable voltage and current referencing

Secondary side regulation in flyback SMPSs

Zener replacement
