Frequently Asked Questions
How does the 25 nA quiescent current of TPS7A0228DBVR benefit a coin-cell powered design?
At 25 nA quiescent current, TPS7A0228DBVR draws negligible standby power from a CR2032 coin cell (rated approximately 220 mAh), allowing the battery to last years in sleep-dominant applications. This makes it a strong choice for IoT sensors, smart meters, and asset trackers where the regulator must stay active even when the load is in deep sleep.
What is the maximum output current and dropout voltage for TPS7A0228DBVR?
TPS7A0228DBVR delivers up to 200 mA output current with a maximum dropout voltage of 0.36 V at full load. The nominal dropout is 0.205 V, which means the input rail only needs to be about 3.05 V to maintain the fixed 2.8 V output, enabling efficient use of partially discharged Li-ion cells operating down to 1.5 V minimum input.
Can TPS7A0228DBVR replace a 2.8 V LDO in a space-constrained PCB layout?
Yes. TPS7A0228DBVR comes in the SOT-23-5 package with a footprint of approximately 1.6 mm x 2.9 mm, making it suitable for compact PCB designs. Its 5-pin configuration includes an enable pin, allowing the host MCU to power-cycle the regulated rail and reduce system power consumption to near zero when the load is unused.
What input voltage range does TPS7A0228DBVR support and how does it handle a 3.6 V Li-ion supply?
TPS7A0228DBVR accepts inputs from 1.5 V to 6 V, so a 3.6 V fully charged Li-ion cell is well within range. The 0.36 V worst-case dropout keeps the 2.8 V output regulated down to approximately 3.16 V input, covering most of the Li-ion discharge curve and ensuring reliable operation across the battery's usable capacity.
