Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the logic condition for the Chip Enable (CE) pin?

The CE pin operates with an Active High logic. A voltage between 1.1V and 28.0V turns the regulator ON, while a voltage between 0V and 0.35V turns it OFF. An open state results in undefined operation.

How does the thermal shutdown circuit function?

The thermal shutdown circuit activates when the junction temperature reaches approximately 150℃, turning off the output. The circuit releases and resumes operation when the junction temperature drops to approximately 125℃, providing a 25℃ hysteresis width.
