Applications
The TPS7A1012PYKAR is optimized for always-on IoT sensor nodes, wearable devices, and wireless SoC-based systems where ultra-low quiescent current directly translates to weeks or months of additional battery runtime. Its 70mV dropout voltage allows the device to keep regulating when a Li-ion cell voltage drops near the end of discharge, squeezing out maximum usable battery energy. The compact DSBGA package also makes it ideal for hearing aids, medical patches, and Bluetooth Low Energy modules with extreme space constraints.

Frequently Asked Questions
What is the output current and dropout voltage of the TPS7A1012PYKAR?
The TPS7A1012PYKAR delivers up to 300mA continuous output current with a maximum dropout voltage of only 70mV (nominal 70mV). This ultra-low dropout means the device can maintain regulation when the input is as little as 70mV above the output, significantly extending usable battery life in portable applications.
What is the input voltage range of the TPS7A1012PYKAR?
The TPS7A1012PYKAR accepts input voltages from 1.7V minimum to 3.3V maximum, with an absolute maximum rating of 3.6V. This range is well suited for single-cell Li-ion/LiPo batteries, 1.8V and 2.5V digital supply rails, and coin cell powered designs operating in the 1.8V to 3V regime.
What package does the TPS7A1012PYKAR use?
The TPS7A1012PYKAR is housed in a 5-ball DSBGA (Die-Size Ball Grid Array) wafer-level chip-scale package, identified by JEDEC code R-PBGA-B5. This extremely small package enables minimal PCB footprint designs for wearables, hearing aids, IoT modules, and medical patches where every square millimeter of board space matters.
Why is low quiescent current important for applications using the TPS7A1012PYKAR?
In always-on battery-powered applications such as IoT sensors, wearables, and Bluetooth beacons, the quiescent (standby) current consumed by the LDO directly drains the battery even when the load is in sleep mode. The TPS7A1012PYKAR's ultra-low IQ (quiescent current) minimizes this self-discharge, extending device battery life from days to weeks or months on a small coin cell or rechargeable cell.
Is the TPS7A1012PYKAR RoHS and Pb-free compliant?
Yes, the TPS7A1012PYKAR carries Pb-free and RoHS-compliant markings (JESD-609 code e1, Pbfree Code: Yes). It meets global environmental directives restricting hazardous substances, making it suitable for products sold in the EU, China, and other regions with strict environmental compliance requirements.
