Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How is the output voltage determined for the AZ1086D-ADJTRE1?

The output voltage is set externally using two resistors connected between the output, adjust, and ground pins according to the formula VOUT = VREF * (1 + R2/R1) + IADJ * R2.

What is the thermal shutdown threshold for this regulator?

The device enters thermal shutdown when the junction temperature reaches 165°C, with a hysteresis of 30°C before it resumes normal operation.
