1.24 V to 6 V adjustable shunt reference — the ±1.5% tolerance is the gate
Its ±1.5% tolerance on the 1.24 V internal reference sets the output accuracy floor for the entire adjustable range up to 6 V. The 80 µA minimum cathode current allows operation in low-bias circuits where a standard TL431's 1 mA minimum would burn too much quiescent power. Maximum output current is 15 mA.
Industrial temperature range and SOT-23-5 footprint
The SOT-23-5 footprint is a standard surface-mount pattern — no special reflow profile beyond the standard lead-free solder process. The SC-74A / SOT-753 case code is electrically identical to the SOT-23-5 supplier device package; the two designations refer to the same 5-pin body.
