LM117 Description

Short technical summary and product information.

The LM117 is an adjustable 3-pin positive voltage regulator from SML, designed to supply currents in excess of 1.5 A over an output voltage range adjustable down to 1.25 V. It provides superior line and load regulation compared to standard fixed regulators.

Key electrical specifications include a typical line regulation of 0.01%/V and a typical load regulation of 0.1%. It also features 80 dB of ripple rejection and a constant current limit that is stable with temperature. The device includes comprehensive overload protection, including current limiting, thermal overload protection, and safe area protection.

This regulator is easy to use, requiring only two external resistors to set the output voltage. It is available in TO-3 and TO packages. While typically no capacitors are needed, an input bypass capacitor may be required if the device is more than 6 inches from input filter capacitors, and an optional output capacitor can improve transient response.

The LM117 is suitable for a wide range of applications, including multifunction printers, AC drive power stage modules, electricity meters, servo drive control modules, and merchant network and server PSUs.
