Thermal Shutdown Function

Thermal shutdown function detects overheating of the regulator and stops the regulator operation to protect the

device from damage. Thermal shutdown circuit stops the regulator operation if the junction temperature becomes

higher than 160°C (Typ.) and restarts the regulator operation if the junction temperature drops below 135°C (Typ.).

The regulator repeats turning on and off and creates pulse waveform until the cause of the overheating is removed.

Adjustable Output Voltage Setting

Output voltage can be adjusted by using the external divider resistors (R1, R2). By using the following equation,
