Frequently Asked Questions
What is the output current and dropout voltage of the TPS74501PQWDRBRQ1?
The TPS74501PQWDRBRQ1 delivers up to 500mA output current with a typical dropout voltage of 225mV and a maximum of 910mV at full load. This low dropout characteristic ensures efficient regulation even with minimal input-to-output voltage differential, reducing power dissipation in automotive battery-powered systems.
Is the TPS74501PQWDRBRQ1 AEC-Q100 qualified for automotive use?
Yes, the TPS74501PQWDRBRQ1 is AEC-Q100 qualified and rated for the automotive temperature range of -40°C to +125°C. The 'Q' in the part number suffix denotes automotive qualification, making it suitable for use in vehicle ECUs, infotainment systems, and ADAS modules that require rigorous reliability screening.
What input voltage range does the TPS74501PQWDRBRQ1 support?
The TPS74501PQWDRBRQ1 accepts input voltages from 1.5V to 6V, covering a broad range of automotive low-voltage rails. This makes it suitable for powering microcontrollers, FPGAs, and analog peripherals from regulated 3.3V or 5V automotive bus lines within an ECU or module.
What package does the TPS74501PQWDRBRQ1 use?
The TPS74501PQWDRBRQ1 is housed in an 8-pin SON (Small Outline No-lead) package, designated JESD-30 code S-PDSO-N8. The exposed pad on the bottom of this package provides excellent thermal dissipation, allowing the LDO to handle full load current even in thermally challenging automotive underdash environments.
Does the TPS74501PQWDRBRQ1 have a power good output, and how is it used?
Yes, the TPS74501PQWDRBRQ1 includes an open-drain power good (PG) output that asserts high when the output voltage reaches the regulation threshold. This pin is commonly used in automotive systems for sequencing multiple power rails, driving reset controllers, or enabling downstream loads only after the supply is stable and within specification.
