PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
This device possesses thermal shutdown (TABS) circuitry as a protection from overheating. For continuous normal operation, the junction temperature should not exceed the thermal-shutdown trip point. If the junction temperature exceeds the thermal-shutdown trip point, the output turns off. When the junction temperature falls below the thermal-shutdown trip point, the output turns on again.
Calculate the power dissipated by the device according to Equation 12.
where
After determining the power dissipated by the device, calculate the junction temperature from the ambient temperature and the device thermal impedance.
