Key Features
- Automotive-grade Q-suffix qualification supports AEC-Q100 compliance for in-vehicle power supply designs
- 500mA output current with 0.4V max dropout voltage maximizes efficiency at low input-to-output differentials
- 0.027% max line regulation and 0.12% max load regulation deliver stable 3.37V output across varying loads
- Wide –40°C to 125°C temperature range in 20-pin TSSOP package suits harsh automotive and industrial environments
Applications
The TPS7133QPWLE is designed for automotive body control modules, ADAS sensor power rails, and infotainment systems requiring a stable, low-noise 3.3V rail derived from a higher vehicle battery-backed supply. It is also used in industrial instruments and motor controllers where a fixed-voltage LDO with low dropout and tight regulation is needed across a wide temperature range. The automotive Q-grade qualification makes it a strong candidate for any AEC-Q100 design requiring high reliability.

Frequently Asked Questions
What is the output voltage and current rating of the TPS7133QPWLE?
The TPS7133QPWLE is a fixed-output LDO with a maximum output voltage of 3.37V and an output current capability of 500mA. The fixed output eliminates the need for external resistor dividers, reducing component count and potential sources of error in the regulated output.
What is the dropout voltage of the TPS7133QPWLE and why does it matter?
The TPS7133QPWLE has a maximum dropout voltage of 0.4V, meaning the input supply only needs to be 0.4V above the output to maintain regulation. This low dropout extends battery life in portable equipment and allows the device to continue regulating when the input supply is close to the output voltage.
Is the TPS7133QPWLE suitable for automotive applications?
Yes, the TPS7133QPWLE carries the 'Q' automotive-grade suffix, indicating it is designed and tested to meet AEC-Q100 reliability requirements. Its –40°C to 125°C operating range and robust line/load regulation specs make it directly applicable to automotive ECU power rails, instrument clusters, and body electronics.
What package does the TPS7133QPWLE use?
The TPS7133QPWLE is housed in a 20-pin TSSOP (Thin Shrink Small Outline Package), JEDEC code R-PDSO-G20. The TSSOP-20 package has a 0.65mm pin pitch and a thin body profile, making it space-efficient for PCB designs with height constraints in automotive and industrial enclosures.
What are the line and load regulation specs for the TPS7133QPWLE?
The TPS7133QPWLE achieves a maximum line regulation of 0.027% and a maximum load regulation of 0.12%. These tight specifications ensure the output voltage remains stable across changes in input voltage and output current load, which is critical in precision analog and RF supply rails.
