What are the key features of REG711EA-3/250G4?
- Charge-pump switched-capacitor architecture supports both step-up and step-down conversion from 1.8 V to 5.5 V input to a fixed 3 V output without inductors
- Ultra-low 5 mA maximum output current is tailored for low-power bias rails such as ADC references, crystal oscillators, and sensor supply domains
- 8-pin MSOP/VSSOP package requires only small external flying capacitors, minimising PCB area in space-constrained portable and wearable designs
What is REG711EA-3/250G4 used for?
The REG711EA-3/250G4 is used to generate a stable 3 V bias rail from a single-cell Li-ion (3.6 V to 4.2 V) or a 2-cell alkaline (2.4 V to 3 V) supply in IoT sensor nodes, RFID readers, and medical wearable devices. Its inductor-free charge-pump topology eliminates EMI from magnetic switching, making it suitable for noise-sensitive analog supply domains such as ADC VREF inputs and RF front-end bias pins. The wide 1.8 V to 5.5 V input range allows the same design to be powered from USB (5 V) or deeply discharged battery cells without circuit changes.
