8.3.3 Load Current

The REF6025, REF6030, REF6033 and REF6041 are specified to deliver current load of ±4mA. The REF6045 is specified to deliver ±3.5mA, and the REF6050 is specified to deliver ±3mA. The REF60xx are protected from short circuits at the output by limiting the output short-circuit current.

The short-circuit current limit (ISC) of the REF60xx family of devices is adjusted by connecting a resistor (RSS) on the SS pin. The short-circuit current limit when the REF60xx device is sourcing current can be calculated as shown in Equation 4:

Equation 4. REF60

The short circuit current limit when the REF60xx device is sinking is calculated as shown in Equation 5:

Equation 5. REF60

The recommended output current of the REF60xx also depends on the resistor connected to the SS pin. The recommended output current (sourcing and sinking) for the REF6025, REF6030, REF6033 and REF6041 is given by Equation 6:

Equation 6. REF60

The recommended output current (sourcing and sinking) for the REF6045 is given by Equation 7:

Equation 7. REF60

The recommended output current (sourcing and sinking) for the REF6050 is given by Equation 8:

Equation 8. REF60

The temperature of the device increases according to Equation 9:

Equation 9. REF60

where:

  • TJ = junction temperature (°C).
  • TA = ambient temperature (°C).
  • PD = power dissipated (W).
  • RθJA = junction-to-ambient thermal resistance (°C/W).

The REF60xx maximum junction temperature must not exceed the absolute maximum rating of 150°C.
