Texas Instruments TLA431/TLA432 All-Capacitor Precision Programmable References are three-terminal adjustable shunt regulators that are stable with all capacitor loads. These modules are pin-compatible with industry-standard TL431 and TL432, but with better stability to support all capacitor loads. The devices feature an output cathode voltage that can be set to values between Vref (2.495V) and 36V, with two external resistors. The TLA431 and TLA432 offer a typical output impedance of 0.2Ω and are specified in two temperature grades, I and Q. The regulators also provide a good stability reference voltage over the entire -40°C to +125°C temperature range. Texas Instruments TLA431/TLA432 All-Capacitor Precision Programmable References are ideal replacements for Zener diodes in many applications, including onboard regulation, switching power supplies, and adjustable power supplies.
