Frequently Asked Questions
Is the PPS74501PQWDRVRQ1 AEC-Q100 qualified for automotive applications?
Yes, the PPS74501PQWDRVRQ1 is AEC-Q100 Grade 1 qualified, covering an ambient temperature range of -40°C to +125°C and a junction temperature up to 150°C. This makes it suitable for under-hood automotive applications including ECU power regulation, sensor supplies, and other harsh automotive power management tasks.
What is the dropout voltage of the PPS74501PQWDRVRQ1?
The PPS74501PQWDRVRQ1 has a typical dropout voltage of 0.72V and a maximum of 0.91V at the full 500 mA output current. This low dropout enables efficient post-regulation from a 1.8V or higher supply rail without requiring a significantly higher input voltage to maintain regulation.
Does the PPS74501PQWDRVRQ1 have a power-good indicator?
Yes, the PPS74501PQWDRVRQ1 includes an open-drain power-good (PG) output pin that asserts high when the output voltage reaches approximately 92% of its target regulation voltage. This allows system sequencing logic or a microcontroller to detect when the supply rail is stable before enabling dependent downstream loads.
What package is the PPS74501PQWDRVRQ1 offered in?
The PPS74501PQWDRVRQ1 is housed in a 6-pin no-lead package (JESD-30 S-PDSO-N6), a compact SMT package that minimizes board area consumption — a key advantage in space-constrained automotive ECU and ADAS module designs where multiple power supply ICs must fit within a small PCB area.
