Frequently Asked Questions
What triggers a RESET signal from this regulator?
The reset pin goes low if the voltage drops below 4.5% of its typical OUT value for more than 2.0 seconds, or if the Watchdog Input (WDI) signal falls outside its limits.
What is the device's low-power consumption in sleep mode?
The quiescent current in sleep mode is very low, rated at a maximum of 50 µA.
What are the operating temperature ranges for this component?
Its junction temperature range (T) is from -40 to +150 °C, making it suitable for automotive environments.
How is the Watchdog function utilized in the system?
The Watchdog function monitors the falling edge of an incoming digital pulse train signal generated by the system microprocessor on pin 6.
