The Micrel MIC5305-3.3YD5TR is a high-performance, fixed 3.3V low dropout linear regulator designed for portable and noise-sensitive electronics. It delivers up to 150mA with an exceptionally low dropout voltage of 0.11V, enabling efficient operation from low-voltage supplies. With a low quiescent current of 150μA and excellent PSRR of up to 85dB, it provides clean, stable power for RF, audio, and precision analog circuits while extending battery life.
- Ultra-Low Dropout: 0.11V at 150mA allows operation from very low input voltages, reducing power loss and heat.
- Excellent PSRR: 85dB to 65dB (1kHz-10kHz) ensures superior rejection of power supply noise, critical for RF and audio.
- Low Quiescent Current: 150μA quiescent current significantly extends battery life in portable devices.
- Compact Package: TSOT-23-5 package saves board space, ideal for miniaturized designs.
