Key Features
- Ultra-low 1 µA quiescent current extends battery life in always-on IoT nodes, wearables, and energy-harvesting designs without sacrificing 200 mA output capability
- Only 308 mV maximum dropout voltage at 200 mA allows efficient regulation from Li-ion cells (2.5 V–4.2 V) down to 3.0 V rails while minimising thermal dissipation
- Excellent line and load regulation (0.018% and 0.062% max respectively) in a tiny 3-pin SOT-23 package, minimising PCB space and BOM complexity
Applications
The PS7A0530PDBZR is designed for always-on power rails in IoT sensor nodes, wearable electronics, and wireless beacons where the 1 µA IQ directly extends battery run-time. Its 200 mA output current and low 308 mV dropout make it an efficient post-regulator behind Li-ion or AA battery stacks supplying 3.3 V microcontrollers and radios. The compact SOT-23 footprint suits space-constrained designs such as smart cards, coin-cell-powered tags, and portable medical monitoring patches.

Frequently Asked Questions
How does the PS7A0530PDBZR's 1 µA quiescent current impact battery life in a coin-cell IoT sensor?
At 1 µA quiescent current, the PS7A0530PDBZR draws only 8.76 mAh per year from the supply during standby, compared to 87.6 mAh for a 10 µA IQ regulator. On a 220 mAh CR2032 coin cell with the MCU sleeping most of the time, this IQ saving alone can extend system life by more than 12 months.
What is the minimum input voltage the PS7A0530PDBZR requires to maintain a 3.0 V regulated output at 200 mA load?
The maximum dropout voltage is 308 mV at 200 mA, so the minimum input voltage needed for a 3.0 V output at full load is approximately 3.31 V. This allows the device to keep regulating even when a Li-ion cell discharges to 3.5 V, which is within the specified 3.5 V minimum input voltage.
How does the PS7A0530PDBZR's load regulation compare to competing LDOs for precision analog supplies?
The PS7A0530PDBZR specifies a maximum load regulation of 0.062%, meaning the output voltage shifts less than 0.62 mV per volt of nominal output across its 0 mA to 200 mA load range. This low figure makes it suitable for ADC reference supplies and sensor bias rails in portable instruments where output stability is critical.
Does the PS7A0530PDBZR suit a 5 V USB-powered charger circuit feeding a 3.3 V microcontroller?
Yes. With a 5 V USB input well within its 3.5 V to 5.5 V input range and a 1.7 V headroom above the 3.3 V output, the dropout constraint is easily satisfied. The 200 mA output current is sufficient for most low-power microcontrollers and their peripherals, and the 3-pin SOT-23 package adds minimal board area to the USB charger PCB.
