are protected from short circuits by limiting the output short-circuit current to 18 mA. The device temperature

increases according to Equation 4:

The REF34-Q1 maximum junction temperature must not exceed the absolute maximum rating of 150°C.

9.4 Device Functional Modes

9.4.1

EN Pin

When the EN pin of the REF34-Q1 is pulled high, the device is in active mode. The device must be in active

mode for normal operation. The REF34-Q1 can be placed in a low-power mode by pulling the ENABLE pin low.

When in shutdown mode, the output of the device becomes high impedance and the quiescent current of the

device reduces to 2 µA in shutdown mode. The EN pin must not be pulled higher than VIN supply voltage. See

the Thermal Information for logic high and logic low voltage levels.
