description/ordering information

The TLVH431 and TLVH432 are low-voltage 3-terminal adjustable voltage references with specified thermal

stability over applicable industrial and commercial temperature ranges. Output voltage can be set to any value

between V

(1.24 V) and 18 V with two external resistors (see Figure 2). These devices operate from a lower

REF

voltage (1.24 V) than the widely used TL431 and TL1431 shunt-regulator references.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

SLVS555D – NOVEMBER 2004 – REVISED FEBRUARY 2005

description/ordering information (continued)

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 SOT23-3 and SOT-89

packages.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. Voltage values are with respect to the anode terminal, unless otherwise noted.

2. Maximum power dissipation is a function of T (max), θ , and T . The maximum allowable power dissipation at any allowable

Figure 18. Flyback With Isolation Using TLVH431 and TLVH432 as Voltage Reference and Error Amplifier

Figure 18 shows the TLVH431 used in a 3.3-V isolated flyback supply. Output voltage V can be as low as

O

reference voltage V

(1.24 V). The output of the regulator plus the forward voltage drop of the optocoupler

REF

LED (1.24 + 1.4 = 2.64 V) determine the minimum voltage that can be regulated in an isolated supply

configuration. Regulated voltage as low as 2.7 Vdc is possible in the topology shown in Figure 18.
