The MIC5211-3.3BM6 is a dual-output low dropout linear regulator from Micrel, delivering a fixed 3.3V from each channel with up to 80mA of current. Its low 0.5V dropout at 50mA and 450µA quiescent current make it well-suited for battery-operated equipment. Housed in a compact SOT-23-6 package, this regulator provides a simple and reliable power solution for multi-rail applications.
- Dual Independent Outputs: Two 3.3V rails in one package reduce component count and board space.
- Low Dropout Voltage (0.5V @ 50mA): Maximizes efficiency by allowing operation close to the battery's end-of-life voltage.
- Low Quiescent Current (450µA): Helps prolong battery life in always-on and standby modes.
- Compact SOT-23-6 Package: Ideal for space-constrained designs.
Dual-Supply Sensor Systems
Use the dual 3.3V outputs to power two separate analog sensors or a sensor and its reference, ensuring a stable and noise-free supply for accurate measurements.
Battery-Powered Portable Devices
The 450µA quiescent current and low dropout voltage make it ideal for extending battery life in handheld instruments, remote controls, and wearable devices.
Multi-Channel DAC/ADC Reference Supplies
Provide independent, clean 3.3V rails to the analog and digital sections of a data converter, minimizing cross-talk and improving signal integrity.
Low-Power Microcontroller I/O and Logic
Power a low-voltage MCU core and its I/O ring from separate 3.3V outputs, preventing digital switching noise from affecting sensitive analog peripherals.
Compact IoT Modules
The SOT-23-6 package and dual outputs allow for a space-efficient power management solution in space-constrained IoT nodes and smart sensors.
Redundant Supply for Critical Memory
Use the two outputs to power volatile memory and a backup power domain, ensuring data retention during brief supply dips.
