Thermal Sensor
Sensor
The thermal sensor protects the device if the junction temperature exceeds the safe value (Tj=150
°C). This temperature rise can be caused by extreme heat, excessive power dissipation caused by
large output voltage drops, or excessive output current. The regulator will shut off when the
temperature exceeds the safe value. As the junction temperature decreases, the regulator will
begin to operate again. Under sustained fault conditions, the regulator output will oscillate as the
device turns off then resets. Please improve heat radiation or lower the input electric power. When
heat radiation is poor, the forecast package loss is not obtained.
* In the case that the power, Vin
× Ishort(Short Circuit Current), becomes more than twice of the maximum rating of its power
dissipation in a moment, there is a possibility that the IC is destroyed before internal thermal protection works.
Reverse Bias Current
The reverse bias protection prevents excessive current from flowing
through the IC even if the input voltage becomes 0 with
voltage impressed on the output side (input short-circuited to
GND). The maximum reverse bias voltage is 6V.
