The LM317HVT/NOPB from Texas Instruments is a versatile 3-terminal adjustable positive voltage regulator. It is designed to supply currents of 1.5A or more, with an output voltage range from 1.25V to 57V. This regulator requires only two external resistors to set the desired output voltage, simplifying circuit design.
Key electrical characteristics include a typical line regulation of 0.01%/V and a load regulation of 0.1%. It also provides a typical ripple rejection of 80dB. The device incorporates internal protection features such as current limiting, thermal overload protection, and safe area protection, making it robust against various fault conditions.
The LM317HVT/NOPB is housed in a TO-220-3 package, suitable for through-hole mounting. The operating temperature range is specified from 0°C to 125°C. This regulator is well-suited for applications requiring adjustable voltage outputs with good regulation and protection.
While typically no external capacitors are needed, an input bypass capacitor may be required if the device is situated more than 6 inches from input filter capacitors. An optional output capacitor can be added to improve transient response. The adjustment terminal can also be bypassed to achieve very high ripple rejection ratios.
