DESCRIPTION/ORDERING INFORMATION (CONTINUED)

TLVH431, TLVH431A, TLVH431B

TLVH432, TLVH432A, TLVH432B

LOW-VOLTAGE ADJUSTABLE PRECISION SHUNT REGULATORS

SLVS555F – NOVEMBER 2004 – REVISED OCTOBER 2005

When used with an optocoupler, the TLVH431 and TLVH432 are ideal voltage references in isolated feedback

circuits for 3-V to 3.3-V switching-mode power supplies. They have a typical output impedance of 0.25

Ω. Active

output circuitry provides a very sharp turn-on characteristic, making the TLVH431 and TLVH432 excellent

replacements for low-voltage Zener diodes in many applications, including on-board regulation and adjustable

power supplies.

The TLVH432 is identical to the TLVH431, but is offered with different pinouts for the SOT-23-3 and SOT-89

packages.
