10.3 Power Dissipation
The REF50xx family is specified to deliver current loads of ±10 mA over the specified input voltage range. The
temperature of the device increases according to the equation:
T_J = T_A + P_D × R_θJA
where
• T_J = Junction temperature (°C)
• T_A = Ambient temperature (°C)
• P_D = Power dissipated (W)
• R_θJA = Junction-to-ambient thermal resistance (°C/W)
(3)
The REF50xx junction temperature must not exceed the absolute maximum rating of 150°C.
