10.3.3 Load Current

The REF34-Q1 family is specified to deliver a current load of ±10 mA per output. The VREF output of the device

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

increases according to Equation 4:

(4)

where

• TJ = junction temperature (°C),

• TA = ambient temperature (°C),

• PD = power dissipated (W), and

• RθJA = junction-to-ambient thermal resistance (°C/W)

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

10.4 Device Functional Modes

10.4.1 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

Thermal Information for logic high and logic low voltage levels.
