Output voltage is adjustable from a 1.24 V minimum up to 6 V maximum via two external resistors. The 100 µA minimum cathode current keeps the reference biased in its linear region; below that the shunt loses regulation. Maximum output current is 15 mA, which sets the upper bound on the resistor divider current plus any load the reference directly drives.
Yes, the TLV431BIDBVT is pin-compatible with the industry-standard TL431 in the SOT-23-5 package. The key difference is the TLV431B's lower minimum reference voltage (1.24 V vs 2.495 V for the TL431) and tighter ±0.5% tolerance. Check that your design's feedback divider and bias resistor values accommodate the 1.24 V reference threshold.
