The LM1117IMP-ADJ/NOPB is an adjustable linear regulator from Texas Instruments, offering up to 800mA output current. With a low dropout of 1.2V at full load and 75dB PSRR, it provides clean, flexible power. The SOT-223-4 package is ideal for space-constrained designs.
- Adjustable Output: Set any voltage from 1.25V to 13.8V with two resistors.
- High Current: 800mA capability for demanding loads.
- Low Dropout: 1.2V dropout improves efficiency with lower input voltages.
- Compact Package: SOT-223-4 saves board space.
Adjustable Power Supply
Provides a flexible output voltage (e.g., 13.8V) for bench supplies or custom rails. The 800mA capacity supports moderate loads.
Battery Charger
Used in 12V lead-acid charger circuits; the adjustable output allows precise float voltage setting.
FPGA/ASIC Core Supply
Regulates down to lower voltages (e.g., 1.8V) with external resistors. The low dropout (1.2V) maximizes efficiency.
Audio Equipment
Provides clean adjustable rails for audio circuits. The 75dB PSRR reduces noise.
Automotive Electronics
Converts 12V battery to 5V or adjustable for sensors. The SOT-223 package is compact for PCB mounting.
LED Driver Reference
Sets a stable voltage for LED constant-current drivers.
