Applications
TPS7350QPE4 provides a stable 5V regulated output in prototyping, test equipment, and legacy industrial boards where through-hole PDIP packaging is preferred or required. Its low 146mV dropout voltage makes it effective in 5V-to-5V regulation scenarios powered from 6V to 10V unregulated wall adapters or battery packs. The device also suits embedded control boards where 0.5A is sufficient for powering microcontrollers, sensors, and small peripherals from a single linear regulator.

Frequently Asked Questions
What is the dropout voltage of TPS7350QPE4 and at what output current does it apply?
TPS7350QPE4 has a typical dropout voltage of 146mV and a maximum of 230mV at 0.5A output current. This low dropout enables regulation from input voltages as low as 5.33V when supplying a fixed 5V output, which is useful in battery-backup and adapter-powered systems with limited headroom above the regulated output.
What input voltage range does TPS7350QPE4 support for safe operation?
TPS7350QPE4 operates from a minimum input of 5.33V up to a maximum of 10V, with an absolute maximum rating of 11V. This range accommodates common 6V, 7.5V, and 9V unregulated DC adapter supplies, allowing the regulator to maintain a clean 5V output at up to 0.5A across the full input range without exceeding safe operating limits.
When should an engineer choose TPS7350QPE4 over an SMD LDO for a 5V power supply design?
TPS7350QPE4 in an 8-pin PDIP package is the right choice for prototype boards using breadboards or perfboard, repair/replacement scenarios on legacy PCBs, and low-volume industrial equipment where through-hole soldering is the production norm. For surface-mount production designs requiring the same 5V at 0.5A, a SOIC or SOT-223 variant would reduce board area while TPS7350QPE4's PDIP format prioritizes ease of handling and manual assembly.
How does the 0.5A current rating of TPS7350QPE4 compare to the load requirements of typical microcontroller systems?
A 0.5A (500mA) output covers most microcontroller-based systems: a typical 32-bit MCU draws 50mA to 150mA, and common peripherals such as Wi-Fi modules draw up to 250mA peak. TPS7350QPE4 can simultaneously supply a microcontroller, a small LCD, and 1 to 2 sensor modules within its 500mA budget, making it adequate for moderate embedded designs without requiring a higher-current regulator.
