The MIC5314-F4YMT is a dual-output LDO from Micrel, delivering fixed 1.2V and 1.5V 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.
DDR3/DDR4 Memory Power
The 1.2V and 1.5V outputs align with DDR3 (1.5V) and DDR4 (1.2V) VDDQ requirements, making it suitable for memory modules in embedded systems.
Portable Audio Players
With 65dB PSRR at 1kHz, this LDO provides clean power for audio DACs and amplifiers, reducing audible noise and distortion.
Smart Home Hubs
The dual outputs can power both the main application processor (1.2V) and wireless communication module (1.5V) in smart home devices.
Industrial Sensors
For low-power industrial sensors, the 12 µA quiescent current and stable outputs ensure reliable operation over extended periods.
Battery Management Systems
In BMS for portable electronics, this LDO can power the fuel gauge (1.5V) and protection circuit (1.2V) from a single regulator.
Set-Top Boxes
The dual outputs can supply the SoC core (1.2V) and HDMI interface (1.5V) in compact set-top box designs.
