Working principle

TL751L12CDR is a three pin voltage regulator IC, its datasheet states that it has adjustable output voltage range of 1.25V~37V. It works on the principle of feedback control, and produces a stabilized output voltage with high accuracy. The input voltage is applied across pin1 and pin2, while the output voltage is available through pin3.

In the internal circuit protection of TL751L12CDR, there is a thermal shutdown circuit, which will shut down the IC and disconnect the output if the junction temperature rises beyond 150°C. There is also an active current limiting and short circuit protection, which will limit the output current to a safe level to prevent over heating and damage to the IC.
