The LM1117DTX-3.3/NOPB is a fixed 3.3V linear regulator from Texas Instruments, offering up to 800mA output current. With a dropout voltage of 1.2V at full load and 75dB PSRR at 120Hz, it ensures clean, stable power for digital ICs. The TO-252-3 package allows compact PCB layouts with adequate heat dissipation. Ideal for microcontrollers, FPGAs, and wireless modules.
- Fixed 3.3V Output: No external resistors needed, simplifying design.
- High Current: 800mA supports multiple digital loads simultaneously.
- Low Dropout: 1.2V at 800mA enables operation from 5V or 4.5V rails.
- Low Quiescent Current: 5 mA reduces power consumption in battery devices.
