Frequently Asked Questions
How does the 1 µA quiescent current of TPS7A051825PYKAR extend battery life in an always-on IoT sensor design?
With only 1 µA quiescent current, the TPS7A051825PYKAR draws negligible standby power, allowing a 200 mAh coin cell to sustain the regulator bias alone for over 20,000 hours without any load. In a typical IoT sensor that sleeps most of the time and wakes for short 10 ms bursts at 50 mA, the regulator overhead is dominated by the 1 µA IQ rather than active current, extending operational battery life by months compared to regulators with 50 µA or higher IQ.
What is the minimum input voltage required to maintain regulation on the 1.8 V output of TPS7A051825PYKAR?
The TPS7A051825PYKAR requires a minimum input voltage of 2.325 V to begin regulation, and with a 204 mV nominal dropout voltage on the 1.8 V rail, the minimum usable input is approximately 2.0 V at full load. This low dropout characteristic makes it suitable for single-cell Li-ion batteries discharging from 4.2 V down to near end-of-life at 2.5 V, ensuring the 1.8 V output remains regulated throughout nearly the entire battery discharge curve.
For a compact wearable PCB, what are the physical dimensions and package type of the TPS7A051825PYKAR?
The TPS7A051825PYKAR is housed in a 4-ball BGA package (JESD-30 code S-PBGA-B4), one of the smallest LDO footprints available, enabling very tight component placement on smartwatch or fitness band PCBs where space is at a premium. The 200 mA maximum output current and 5.5 V absolute maximum input rating are compatible with the power budgets of most BLE and ultra-low-power MCU circuits found in wearable health monitoring devices.
How does the TPS7A051825PYKAR compare to standard LDOs when powering a 2.5 V sensor from a 3.3 V rail?
Powering a 2.5 V output from a 3.3 V input gives only 800 mV of headroom, which many standard LDOs with 300 mV to 500 mV dropout cannot reliably support at 200 mA load. The TPS7A051825PYKAR with its 382 mV maximum dropout voltage maintains regulation with 420 mV of margin, while its ultra-low 1 µA IQ ensures the regulator itself contributes negligible power loss compared to alternatives with 100 µA or higher bias current.
