The MIC5314-G4YMT is a dual-output, low-dropout linear regulator from Micrel, delivering fixed 1.2V and 1.8V rails. Each channel supports up to 300mA with a low 0.2V dropout, making it efficient for battery-operated systems. Its ultra-low 12 µA quiescent current extends standby time in portable electronics. The 12-TMLF® package measures just 2.5x2.5mm, ideal for space-constrained designs. With 65dB PSRR at 1kHz, it provides clean, stable power for noise-sensitive analog and RF circuits.
- Extended Battery Life: Ultra-low 12 µA quiescent current minimizes power draw in standby mode, ideal for always-on IoT devices.
- Compact Dual-Rail Solution: Two 300mA outputs in a 2.5x2.5mm package save PCB space versus two separate LDOs.
- Clean Power Delivery: 65dB PSRR at 1kHz filters supply noise, ensuring stable operation for sensitive analog loads.
- Low Dropout Operation: 0.2V dropout at full load allows operation from nearly depleted batteries, maximizing usable capacity.
Battery-Powered IoT Sensors
The 12 µA quiescent current and dual 1.2V/1.8V outputs are ideal for powering low-power microcontrollers and RF transceivers in wireless sensor nodes, extending battery life significantly.
Portable Medical Devices
With 65dB PSRR at 1kHz, this LDO provides clean, stable power for sensitive analog front-ends in glucose monitors and pulse oximeters, reducing noise-induced measurement errors.
Smartphone Camera Modules
The dual outputs can power both the image sensor (1.8V) and the autofocus driver (1.2V) from a single LDO, saving board space in space-constrained camera modules.
Wearable Fitness Trackers
The 2.5x2.5mm TMLF package and low dropout of 0.2V at 300mA make it suitable for powering Bluetooth SoCs and accelerometers in compact wearables where efficiency and size are critical.
FPGA Core and I/O Supplies
For small FPGAs requiring separate core (1.2V) and I/O (1.8V) voltages, this dual regulator provides a simple, single-chip solution with adequate 300mA per rail.
Audio Codec Power
The 40dB PSRR at 20kHz helps suppress high-frequency switching noise, ensuring clean power for audio codecs in portable media players and headsets.
