The MCP1754ST-3302E/DB from Microchip Technology is a fixed 3.3V low dropout regulator rated for 150mA. It features a low quiescent current of 90 µA and a dropout voltage of 0.5V at full load. The 72dB PSRR at 1kHz ensures stable operation in noise-sensitive environments. Packaged in a SOT-223-3, it offers a good balance of thermal performance and board space for portable and industrial designs.
- Ultra-Low Quiescent Current: 90 µA extends battery life in standby and always-on systems.
- Stable Output: 72dB PSRR at 1kHz rejects high-frequency noise for sensitive loads.
- Low Dropout: 0.5V at 150mA allows efficient regulation from 3.8V inputs.
- Thermally Efficient Package: SOT-223-3 with exposed pad improves heat dissipation.
