TLVH431A
- Low-voltage operation: down to 1.24 V
- Reference voltage tolerances at 25°C
- 0.5% for B grade
- 1% for A grade
- 1.5% for standard grade
- Adjustable output voltage, VO = VREF to 18 V
- Wide operating cathode current range: 100 µA to 70 mA
- 0.25-Ω typical output impedance
- –40°C to +125°C specifications
- TLVH432 provides alternative pinouts for SOT-23-3 and SOT-89 packages
- Ultra-small SC-70 package offers 40% smaller footprint than SOT-23-3
The TLVH431 and TLVH432 devices 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 VREF (1.24 V) and 18 V with two external resistors (see Figure 7-2). These devices operate from a lower voltage (1.24 V) than the widely used TL431 and TL1431 shunt-regulator references.
When used with an optocoupler, the TLVH431 and TLVH432 devices 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 devices excellent replacements for low-voltage Zener diodes in many applications, including on-board regulation and adjustable power supplies.
The TLVH432 device is identical to the TLVH431 device, but is offered with different pinouts for the 3-pin SOT-23 and SOT-89 packages.
