The LM1117IDT-5.0/NOPB is a fixed 5V low dropout linear regulator from Texas Instruments. It delivers up to 800mA of output current with a dropout voltage of just 1.2V at full load. The device features a low quiescent current of 5mA and excellent ripple rejection of 75dB at 120Hz, making it suitable for noise-sensitive applications. Housed in a compact TO-252-3 package, it offers thermal protection and current limiting for robust operation in industrial and consumer electronics.
- High Output Current: 800mA capability supports power-hungry digital loads without external pass transistors.
- Excellent Ripple Rejection: 75dB PSRR at 120Hz ensures clean output for audio and precision analog circuits.
- Low Dropout: 1.2V dropout allows efficient regulation from 6.2V inputs, reducing power dissipation.
- Thermal Protection: Internal current limiting and thermal shutdown safeguard the regulator and load.
5V Digital Logic Power
Provides a stable 5V rail for microcontrollers, FPGAs, and digital ICs. The 800mA capacity supports multiple peripherals, and the 75dB PSRR at 120Hz filters mains ripple effectively.
Industrial Sensor Interfaces
Regulates 5V for analog sensor front-ends. Low output noise and high PSRR ensure accurate ADC readings in noisy factory environments.
Automotive Infotainment
Converts vehicle battery voltage (12V) down to 5V for USB hubs and display controllers. The TO-252 package handles thermal dissipation from high input-to-output differentials.
Battery-Powered Instruments
Regulates 5V from a 6-9V battery pack. The 5mA quiescent current is acceptable for bench instruments where battery life is secondary to stability.
Networking Equipment
Powers 5V PHY transceivers and switch ICs. The 1.2V dropout allows operation from a 6.2V rail with margin, ensuring reliable link stability.
Audio Preamplifiers
Provides clean 5V for op-amp stages. The 75dB PSRR at 120Hz rejects power supply hum, preserving audio signal integrity.
