LM317LCD Description

Short technical summary and product information.

The LM317LCD from Texas Instruments is an adjustable linear voltage regulator designed for applications requiring up to 100mA of output current. This 3-terminal device offers a wide adjustable output voltage range from 1.25V to 37V, making it versatile for various power supply designs. Its typical input regulation is 0.01% per volt change, and output regulation is typically 0.5%.

 

The regulator features robust protection mechanisms including over current, over temperature, and short circuit protection. It operates within a temperature range of 0°C to 125°C and is supplied in a surface-mount 8-SOIC package. The LM317LCD is easy to implement, requiring only two external resistors to set the desired output voltage, simplifying circuit design.

 

This component is suitable for a broad range of power management tasks where adjustable voltage output is needed. Its typical PSRR is 80dB at 120Hz and 65dB at 100kHz, ensuring clean power delivery. For higher current requirements, alternative parts like the LM317M (500mA) and LM317 (1.5A) are available.
