Texas Instruments Adjustable Linear Voltage Regulator 1.25 V to 38 V 100mA 8-Pin SOIC TL317CD

Texas Instruments TL317CD is a highly reliable adjustable linear voltage regulator packaged in an 8-pin SOIC surface mount device. It offers an output voltage range from 1.25 V up to 38 V when configured with external resistor dividers, supporting a continuous output current of 100 mA. This device is ideal for use in precision voltage regulation tasks in many industrial and electronic applications requiring stable voltage control.

The TL317CD features excellent input and output voltage regulation, with typical input regulation of 0.01% and output regulation of 0.5%, ensuring consistent voltage performance even under varying load conditions. It integrates safe area protection, current limiting, and overload protection to enhance robustness and safeguard against operational faults.

Designed for surface mount technology, the SOIC 8-pin package measures 4.9 mm in length, 3.91 mm in width, and 1.58 mm in height, facilitating compact PCB layouts. Its maximum operating temperature is rated at 125°C, supporting reliable operation in demanding thermal environments.

With a maximum input voltage of 38 V, the TL317CD is well suited to automotive, industrial, and consumer electronics applications where positive adjustable voltage regulation is required. Additionally, its ripple rejection ratio stands at a typical 80 dB, which can be further improved by bypassing the adjustment pin with a capacitor, making it efficient at minimizing output noise.
