Key Features
- PMOS pass element architecture achieving lowest-dropout performance with 0.15V typical and 0.25V maximum dropout voltage
- Wide input voltage range of 5.2V to 10V (absolute max 11V) for compatibility with various power supply rails
- Superior line regulation of 0.037% maximum ensuring stable output voltage under varying input conditions
- 20-pin SOIC package (R-PDSO-G20) with fixed output voltage for reliable and consistent power regulation
Applications
The TPS7348QPW is suited for precision analog and mixed-signal circuits requiring stable low-noise power supplies, such as sensor amplifiers, data acquisition front-ends, and precision reference circuits. Its PMOS architecture eliminates the need for input capacitors in some configurations, simplifying PCB design in space-constrained industrial and communications equipment. The low dropout voltage makes it effective in battery-powered systems operating near the output rail voltage.

Frequently Asked Questions
What is the dropout voltage of the TPS7348QPW and why does it matter?
The TPS7348QPW has a typical dropout voltage of 0.15V and a maximum of 0.25V. Low dropout voltage is critical in applications where the input voltage is only slightly higher than the regulated output, allowing the regulator to maintain regulation even as battery voltage declines or input rails droop under load.
What is the input voltage range for the TPS7348QPW?
The TPS7348QPW accepts input voltages from 5.2V (minimum) to 10V (maximum operating), with an absolute maximum rating of 11V. This range makes it compatible with common 5V, 6V, and 9V power supply rails used in industrial control, audio, and communications equipment.
What package does the TPS7348QPW use?
The TPS7348QPW is housed in a 20-pin Small Outline IC package (JESD-30 code R-PDSO-G20), a standard SOIC-20 surface-mount package. This package is widely supported in PCB design tools and compatible with automated SMT assembly processes in both prototype and production environments.
What is the line regulation performance of the TPS7348QPW?
The TPS7348QPW achieves a maximum line regulation of 0.037%, meaning the output voltage changes by less than 0.037% for variations across the full input voltage range. This tight regulation makes it appropriate for precision analog circuits, sensors, and reference circuits where output voltage stability directly affects measurement accuracy.
What lifecycle stage is the TPS7348QPW currently in?
The TPS7348QPW has a YTEOL (years to end-of-life) value of 0, indicating it may be at or near end-of-life. Designers should verify current production status and availability with authorized Texas Instruments distributors before starting new designs, and consider alternative LDO regulators from the TPS73xx family if long-term availability is required.
