What are the key features of TPS7248QPE4?
- PMOS pass element enables very low dropout voltage of 285 mV maximum for efficient regulation
- Fixed output voltage configuration simplifies BOM and layout for known-voltage rails
- Input voltage range of 5.24 V to 10 V suits 5 V and 9 V supply systems
- 8-pin DIP package facilitates prototyping and through-hole assembly
What is TPS7248QPE4 used for?
The TPS7248QPE4 is suited for powering analog sensors, op-amps, and precision reference circuits that require a low-noise, stable supply derived from a 5 V to 10 V input rail. Its low dropout of 285 mV maximizes efficiency when the input-to-output differential is small, as in battery-powered or regulated bus systems. The through-hole DIP package simplifies use on prototype boards and in serviceability-focused industrial equipment.

Frequently Asked Questions
What is the dropout voltage of TPS7248QPE4 and why does it matter in a 5 V system?
The TPS7248QPE4 has a maximum dropout voltage of 285 mV. In a 5 V input system targeting a fixed 4.75 V output, this low dropout ensures the regulator stays in regulation even when the supply dips to within 285 mV of the output, which is critical for battery-operated or poorly regulated supply rails.
What input voltage range does TPS7248QPE4 accept and which power bus architectures does it fit?
The TPS7248QPE4 accepts input voltages from 5.24 V to 10 V, making it compatible with 5 V USB bus supplies, 6 V battery packs, and 9 V wall adapters. This range covers common embedded and industrial supply voltages, reducing the need for pre-regulation or additional conversion stages before the LDO.
How does the PMOS architecture of TPS7248QPE4 differ from NMOS LDOs in terms of efficiency?
PMOS LDOs like the TPS7248QPE4 use a PMOS pass transistor that does not require a gate drive voltage above the input rail. This allows the dropout voltage to be as low as 285 mV, whereas NMOS-based LDOs typically require the gate to be driven higher than the input, increasing minimum dropout and control circuit complexity in low-headroom applications.
In which type of end equipment is TPS7248QPE4 most commonly used?
The TPS7248QPE4 is commonly used in industrial instrumentation, test equipment, and analog signal conditioning boards where a clean, fixed-voltage supply is needed from a 5 V to 10 V rail. Its through-hole DIP package and low dropout of 285 mV make it especially practical in prototype labs and legacy industrial systems requiring through-hole components.
