What are the key features of TPS75333QPWPREP?
- Fixed 3.3 V output with 1.5 A current capability covers automotive microcontroller and sensor supply requirements
- Ultra-low 160 mV typical dropout voltage minimizes power dissipation and extends battery life in 3.6 V to 5.5 V systems
- AEC-Q100 automotive qualification ensures reliable operation from -40°C to 125°C in harsh vehicle environments
- 20-pin HTSSOP with exposed thermal pad enables efficient heat dissipation for high-current continuous loads
What is TPS75333QPWPREP used for?
TPS75333QPWPREP provides a stable 3.3 V regulated supply for automotive microcontrollers, CAN transceivers, and ADAS sensor modules requiring up to 1.5 A continuous current. Its low 160 mV dropout voltage makes it ideal for single-cell LiFePO4 and 5 V bus-powered automotive electronics where supply headroom is limited. The automotive-grade qualification and wide -40°C to 125°C operating range suit under-hood and instrument cluster applications where thermal stress is a key design constraint.

Frequently Asked Questions
What is the dropout voltage of TPS75333QPWPREP at full 1.5 A load and why does it matter for automotive 5 V systems?
At full 1.5 A load, TPS75333QPWPREP has a typical dropout voltage of 160 mV and a maximum of 300 mV. This low dropout allows the regulator to maintain a stable 3.3 V output from a 5 V supply bus even when the bus sags to 3.6 V under transient load conditions, which is critical in automotive systems where supply rails can drop during engine cranking or high-current actuator switching.
Which automotive temperature grade does TPS75333QPWPREP support and what certifications apply?
TPS75333QPWPREP is AEC-Q100 qualified and operates across the full automotive temperature range of -40°C to 125°C. The device is also RoHS compliant and carries the JESD-609 e4 designation, confirming lead-free construction suitable for modern automotive electronic assemblies in body control modules, ADAS ECUs, and powertrain control units.
How does the exposed thermal pad on the 20-pin HTSSOP package help manage heat dissipation at 1.5 A?
The exposed thermal pad on the 20-pin HTSSOP package of TPS75333QPWPREP provides a direct thermal path to the PCB ground plane, significantly reducing junction-to-ambient thermal resistance compared to a standard SOIC package. At 1.5 A with 300 mV dropout, the device dissipates up to 450 mW; connecting the exposed pad to a 645 mm² copper pour on the PCB can keep junction temperature below 125°C in a 85°C ambient environment.
When should a designer choose TPS75333QPWPREP over a switching regulator for automotive 3.3 V supply design?
TPS75333QPWPREP is preferred over a switching regulator when design simplicity, low EMI, and fast transient response are priorities, particularly for analog sensor supply rails in automotive systems. The LDO introduces no switching noise, which is critical for 12-bit or higher ADC reference supply circuits. At load currents below 500 mA with a 5 V input, the power difference between the LDO and a buck converter is less than 1 W, making the simpler 20-pin HTSSOP solution more cost-effective.
