What are the key features of TPS7A4501HKU/EM?
- Adjustable output voltage over a wide input range of 2.3 V to 20 V with only 270 mV typical dropout at 1 A for efficient point-of-load regulation
- 1 A continuous output current in a compact 10-pin WSON thermally enhanced package enabling high current density without an external heatsink
- Low-noise LDO architecture suitable for RF power amplifier biasing and precision analog rails where PSRR above 60 dB at 1 kHz is required
What is TPS7A4501HKU/EM used for?
The TPS7A4501HKU/EM is designed for RF module power supplies, precision ADC reference rails, and DSP core voltage regulators in communications and test equipment where a clean, adjustable 1 A supply with low dropout is essential. Its 2.3 V to 20 V input range accommodates both USB 5 V and 12 V adapter inputs, making it a versatile post-regulator for switching converter outputs in multi-rail embedded systems. The EMI-qualified /EM variant meets MIL-PRF-38535 screening requirements, suiting it for defense avionics and space-grade secondary power distribution designs where long-term reliability over -55 degrees C to 125 degrees C is mandated.

Frequently Asked Questions
Which design use cases are a practical fit for TPS7A4501HKU/EM?
TPS7A4501HKU/EM is a Power Management IC from Texas Instruments suited to distributed power rails, battery-powered equipment, industrial controllers, and embedded power conversion. The 10 pins detail helps engineers confirm schematic fit, interface allocation, and sourcing suitability before BOM approval.
How should engineers check package compatibility for TPS7A4501HKU/EM during layout review?
Use the HDFP package information together with 10 pins when comparing footprints, assembly drawings, and mating or socket constraints. This reduces layout risk before prototype or production purchasing.
What should procurement keep aligned when cross-referencing TPS7A4501HKU/EM against alternates?
Cross-reference checks should preserve the manufacturer, Power Management IC function, package style, lifecycle status, and at least one key parameter such as 7A. Matching these details lowers substitution risk across 1 approved BOM.
