Frequently Asked Questions
How does the REG711EA-3.3/250G4 provide a 3.3 V rail without inductors for a noise-sensitive sensor circuit?
The REG711EA-3.3/250G4 uses a switched-capacitor charge-pump topology to convert input voltages of 1.8 V to 5.5 V to a fixed 3.3 V output at up to 50 mA without inductors. Eliminating magnetic components reduces EMI, making it ideal for noise-sensitive analog sensors, RF front-ends, and microcontroller supply rails in compact portable designs.
Can the REG711EA-3.3/250G4 power a microcontroller from a 2-cell AA battery pack without a separate boost converter?
Yes. A 2-cell AA pack provides approximately 3 V, which is within the REG711EA-3.3/250G4 input range of 1.8 V to 5.5 V, allowing the converter to produce its fixed 3.3 V output at up to 50 mA. This directly powers a 3.3 V microcontroller and associated peripherals without needing an additional boost stage, simplifying the power tree design.
How many low-power peripherals can the REG711EA-3.3/250G4 simultaneously supply within its 50 mA output budget?
The REG711EA-3.3/250G4 delivers up to 50 mA at 3.3 V. This budget can simultaneously supply a BLE module at approximately 15 mA, a MEMS sensor at 5 mA, and a low-power microcontroller at 10 mA, leaving 20 mA of headroom for additional peripherals, making it a practical single-IC power solution for compact multi-peripheral IoT sensor nodes.
