The MIC5209-3.6YS-TR from Microchip Technology is a fixed 3.6V LDO regulator capable of 500mA output. Its low quiescent current of 170 µA and dropout voltage of 0.6V at full load make it efficient for battery-powered designs. The SOT-223-3 package is compact and thermally adequate for moderate loads. With 75dB PSRR at 120Hz, it delivers clean, stable power for sensitive portable electronics.
- Ultra-Low Quiescent Current: 170 µA extends battery life in always-on applications.
- Low Dropout: 0.6V at 500mA allows operation from nearly depleted batteries.
- High PSRR: 75dB at 120Hz filters mains ripple effectively.
- Compact SOT-223-3: Saves board space in space-constrained designs.
Battery-Powered IoT Sensors
The 170 µA quiescent current extends battery life in wireless sensors, while the 3.6V output suits low-power microcontrollers and RF transceivers.
Portable Medical Devices
With 75dB PSRR at 120Hz, this LDO ensures clean power for glucose monitors and pulse oximeters, reducing noise-induced measurement errors.
Handheld GPS Modules
The 500mA capacity and low dropout of 0.6V allow operation from a 3.7V Li-ion battery down to 4.2V, maintaining stable 3.6V for navigation processors.
Wearable Electronics
SOT-223-3 package is compact for smartwatches, and the low quiescent current supports always-on display and sensor polling.
Industrial Sensor Interfaces
Stable 3.6V rail for 3.3V logic with margin, plus high PSRR rejects motor noise in factory automation environments.
Audio Codec Power
Low noise and 75dB ripple rejection make it suitable for powering audio codecs in portable recorders.
