LM317LCPK Description

Short technical summary and product information.

The LM317LCPK from Texas Instruments is an adjustable linear voltage regulator designed for applications requiring up to 100mA of output current. This device offers a wide adjustable output voltage range, from 1.25V to 37V for new chips and 1.25V to 32V for legacy chips. It requires only two external resistors to set the output voltage, simplifying circuit design.

 

The regulator operates within a temperature range of 0°C to 125°C and features protection mechanisms against over current, over temperature, and short circuits. Its typical input regulation is 0.01% per input voltage change, and output regulation is typically 0.5%. Ripple rejection is rated at 80dB at 120Hz and 65dB at 100kHz.

 

Packaged in a SOT-89-3 (TO-243AA) surface-mount package, the LM317LCPK is suitable for various electronic designs. It is supplied in a standard package quantity of 1000 units on a large tape and reel.

 

For applications requiring higher output currents, consider the LM317M (500mA) or LM317 (1.5A) from Texas Instruments.
