Frequently Asked Questions
How does the 1 µA quiescent current of the PS7A0527PDBZR benefit a coin-cell powered IoT sensor?
With only 1 µA quiescent current, the PS7A0527PDBZR draws negligible power in standby, allowing a 220 mAh coin-cell battery to sustain years of operation in duty-cycled IoT sensors that sleep most of the time between measurements.
What is the maximum output current and dropout voltage of the PS7A0527PDBZR?
The PS7A0527PDBZR provides up to 200 mA output current with a maximum dropout voltage of 0.308 V, enabling reliable 3.3 V regulation from a 3.6 V lithium cell even as the battery discharges toward end-of-life.
Which input voltage range does the PS7A0527PDBZR support, and is it compatible with 5 V USB-powered circuits?
The PS7A0527PDBZR accepts input voltages from 3.2 V to 5.5 V, covering both single-cell Li-ion battery rails (approximately 4.2 V) and USB 5 V sources, making it versatile for dual-mode portable devices that switch between battery and USB power.
