TPS768: Thermal Resistance Information

Tank.Xue

Part Number: TPS768

Hi team,

I would like to request for the thermal resistance information ( junction-to-ambient for the package--Rθja) of following devices:

1. TPS76801QDR (SOIC-8)

2. TPS76801QPWP (HTSSOP-20)

Thank you very much.

Hi Tank.Xue,

The thermal information for TPS768 is found on the second page of the datasheet:

The Derating Factor column is the reciprocal of thermal resistance; the power rating columns give you the max dissipated power the LDO can handle before reaching a junction temperature of 125ºC at different ambient temperatures.

Please look at the table below with the calculated values for thermal resistance:

Package	Derating Factor(mW/ºC)	RθJA(ºC/W)
SOIC-8	5.6818	176
HTSSOP-20	30.7	32.6

Regards,

Andres
