What are the key features of TPS7A0518PYKAR?
- Ultra-low 1 µA quiescent current extends battery life in always-on IoT and wearable designs
- 200-mA output current capability with 204-mV typical dropout voltage for efficient regulation
- Wide input voltage range of 2.3 V to 5.5 V in a tiny 4-ball BGA footprint suitable for space-constrained applications
What is TPS7A0518PYKAR used for?
TPS7A0518PYKAR is ideal for battery-powered IoT sensors, wearables, and portable medical devices where ultra-low quiescent current is critical. Its 200-mA output and sub-250-mV dropout make it well-suited for always-on subsystem rails powered directly from single-cell Li-ion or coin-cell batteries. The tiny BGA package enables integration into space-constrained modules such as wireless sensor nodes and smartwatch power trees.

Frequently Asked Questions
How low is the quiescent current of TPS7A0518PYKAR and why does it matter for battery-powered designs?
The TPS7A0518PYKAR draws only 1 µA of quiescent current in regulation. This ultra-low Iq is critical for always-on IoT devices and wearables that must sustain standby operation for months or years on a coin-cell or Li-ion battery without significant self-discharge.
What input voltage range and maximum output current does TPS7A0518PYKAR support?
The device operates from a 2.3 V minimum to 5.5 V maximum input voltage and delivers up to 200 mA of output current. The typical dropout voltage is only 204 mV at full load, making it highly efficient for single-cell battery applications down to low states of charge.
Which package does TPS7A0518PYKAR use and how does it help board layout in compact designs?
TPS7A0518PYKAR is housed in a 4-ball BGA package. This miniature footprint allows extremely tight board integration, reducing the PCB area needed for the power supply rail in smartwatches, wireless earbuds, and other miniaturized consumer electronics with fewer than 10 mm2 available.
When should an engineer choose TPS7A0518PYKAR over a standard LDO for a sensor node running on a 3 V coin cell?
For a sensor node on a 3 V CR2032 coin cell, TPS7A0518PYKAR draws only 1 µA quiescent current and can deliver 200 mA peak, meaning the regulator drains negligible baseline current between 10 ms active bursts. A standard LDO drawing 50 µA to 100 µA would deplete the same coin cell far faster during idle intervals.
