ZHCSU65D February 2010 – June 2025 TPS73801
PRODUCTION DATA
The power handling capability of the device is limited by the recommended maximum operating junction temperature (125°C). The power dissipated by the device is made up of two components:
The GND pin current can be found using the GND pin current graphs in the Typical Characteristics. Power dissipation is equal to the sum of the two components listed above.
The TPS73801 series regulators have internal thermal limiting designed to protect the device during overload conditions. For continuous normal conditions, the recommended maximum operating junction temperature is 125°C. Careful consideration must be given to all sources of thermal resistance from junction to ambient. Additional heat sources mounted nearby must also be considered.
