What are the key features of PTPS7B7033QPWPRQ1?
- AEC-Q100 automotive qualification for reliable use in harsh vehicle environments
- 300 mA output current with 40 V maximum input handling 12 V and 24 V automotive rails
- Low quiescent current design maximizing efficiency in always-on body-control modules
- Power Good output flag enabling power sequencing and fault monitoring in multi-rail systems
- Fixed 3.3 V positive LDO output eliminating external resistors and simplifying design
What is PTPS7B7033QPWPRQ1 used for?
The PTPS7B7033QPWPRQ1 is designed for automotive body control modules, ADAS sensor nodes, and in-vehicle infotainment subsystems that require a 3.3 V regulated supply from a 12 V or 24 V vehicle battery rail. Its AEC-Q100 screening and 40 V input tolerance allow direct connection to automotive battery lines including load-dump transient conditions up to 40 V. Gateway ECUs, telematics control units, and seat-control modules also use this device for its Power Good signal and low quiescent current during key-off standby operation.

Frequently Asked Questions
What output current and input voltage range does PTPS7B7033QPWPRQ1 support in automotive systems?
The PTPS7B7033QPWPRQ1 delivers up to 300 mA at a fixed 3.3 V output and accepts input voltages up to 40 V, making it directly compatible with 12 V and 24 V automotive battery rails including ISO 7637 load-dump transients encountered in vehicle electronics.
How does the Power Good output of PTPS7B7033QPWPRQ1 improve system reliability in multi-rail ECU designs?
The Power Good indicator asserts a logic-high signal only when the 3.3 V output is within regulation, allowing downstream processors and FPGAs to hold reset until the supply is stable, preventing undefined boot states and reducing soft failures in safety-critical automotive ECU power sequencing scenarios.
What makes PTPS7B7033QPWPRQ1 suitable for always-on body-control modules during key-off standby?
Its low quiescent current design minimizes battery drain when the vehicle ignition is off, ensuring a body-control module monitoring door locks, alarms, or keyless entry can remain powered for days from a 12 V battery without drawing enough current to cause a no-start condition.
Which automotive qualification does PTPS7B7033QPWPRQ1 carry, and what does that mean for production screening?
It is screened to AEC-Q100 Grade 1 level, meaning the device is tested for reliability across the automotive temperature range of -40°C to 125°C and subjected to stress qualification tests including HTOL, HAST, and ESD, ensuring production-ready quality for vehicle-volume supply chains.
