Data sheet:
The TLA431 and TLA432 devices are three-terminal adjustable shunt regulators that are stable with all capacitor loads. The devices are pin compatible with the industry standard TL431 and TL432 but with improved stability to support all capacitor loads. The output cathode voltage can be set to any value between Vref (2.495V) and 36V, with two external resistors. These devices have a typical output impedance of 0.2Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies. The TLA431 also functions as a comparator for undervoltage monitoring. The internal amplifier and reference of the TLA431 is used an error amplifier in isolated optocoupler flyback power supplies. The TLA432 device has exactly the same functionality and electrical specifications as the TLA431 device.
The TLA431 and TLA432 devices are specified in two temperature grades, I and Q. In addition, the devices offer good stability reference voltage over the entire temperature range.
- No output capacitor required
- Stable with all capacitive loads
- Reference voltage tolerance at 25°C
- 1% (A grade)
- Adjustable output voltage: Vref to 36V
- Operation from −40°C to 125°C
- Typical temperature drift (TLA43xA)
- 8mV (I temp)
- 11mV (Q temp)
- Low Output Noise
- 0.2Ω Typical output impedance
- Sink-current capability: 0.2mA to 100mA
- Pin-compatible with industry-standard TL431 and TL432
