The Texas Instruments LM1117ILD-ADJ/NOPB is a versatile adjustable linear regulator delivering up to 800mA of output current. Its output voltage can be set from 1.25V to 13.8V with just two external resistors, providing flexibility for a wide range of applications. With a low dropout voltage of 1.2V and excellent 75dB ripple rejection at 120Hz, it ensures clean, stable power for sensitive analog and digital circuits. The compact 8-WSON package is ideal for space-constrained designs.
- High Output Current: 800mA capability supports demanding loads like FPGAs and multiple sensor arrays.
- Adjustable Output: Voltage set from 1.25V to 13.8V with external resistors, offering design flexibility.
- Excellent Ripple Rejection: 75dB PSRR at 120Hz ensures clean power for audio and precision analog circuits.
- Low Dropout: 1.2V dropout at full load maximizes efficiency in battery-powered systems.
High-Current Adjustable Power Supplies
With 800mA output capability and adjustable voltage up to 13.8V, this LDO is perfect for benchtop power supplies or as a post-regulator for DC-DC converters requiring precise voltage trimming.
Battery-Powered Equipment
The 5mA quiescent current and low dropout of 1.2V make it suitable for battery-operated devices where maximizing battery life and maintaining regulation as the battery discharges is critical.
Audio and Precision Analog Circuits
The excellent 75dB PSRR at 120Hz effectively filters mains-frequency ripple, making it ideal for powering op-amps, DACs, and audio preamplifiers where clean supply rails are essential.
Industrial Sensor Interfaces
Its wide adjustable output range and robust 800mA current capability allow it to power multiple sensors and interface ICs from a single regulated rail, simplifying industrial control board design.
FPGA and DSP Core Supplies
Many FPGAs and DSPs require a low-voltage core supply with high current. The LM1117 can be configured to provide 1.8V, 2.5V, or 3.3V at up to 800mA, meeting the demands of digital processors.
Automotive Infotainment Systems
The wide input range and high current make it suitable for powering infotainment processors and displays from a regulated 5V or 12V automotive bus, ensuring stable operation despite load transients.
