Hello, Please ask a question about LM5017MRX_NOPB Datasheet
# Example questions:
➢ What benefit does this provide and what voltage range is specified for external power?
➢ What minimum esr is required for the output capacitor (c out) for proper regulation, and what component can be added if the esr is too low?
➢ What is the primary function of the 'intelligent current limit off-timer' and how does it adapt its timing based on feedback voltage?
