2017年10月2日 · The LT117A Series are 3-terminal positive adjustable voltage regulators which offer improved performance over earlier devices. A major feature of the LT117A is the output voltage tolerance is guaranteed at a maximum of ±1%, allowing an overall power supply tolerance to be better than 3% using inexpensive 1% resistors.

LT117A 系列是三端正电压可调稳压器，其可提供优于先前同类器件的性能。 LT117A 的一个主要特点是输出电压容限保证为 ±1% (最大值)，因而在使用廉价的 1% 电阻器时可实现优于 3% 的总电源容限。 电压和负载调节性能也得到了改善。 此外，当在满负载、电压和功率耗散情况下运作时，LT117A 基准电压保证不超过 2%。 LT117A 可调稳压器提供了一款适合所有正电压稳压器要求的改进型解决方案，其可输送高达 1.5A 的负载电流。 如需了解性能曲线和应用电路，请参阅 …

Title: LT117A/LT317A/LM117/LM317 - Positive Adjustable Regulator Author: Linear Technology Corporation Subject |1055|1040|1003|1603|1503|1778| Keywords

Description: Positive Adjustable Regulator. Manufacturer: Linear Technology.

The LM317A adjustable 3-terminal, positive-voltage regulators are capable of supplying current in excess of 1.5 A over a 1.25-V to 37-V output range and provide 1% output-voltage accuracy. Both line regulation and load regulation are better achieved with the LM317A device than with standard fixed regulators.

A major feature of the LT117A Is I Min. 1.5A Output Current the output voltage tolerance is guaranteed at a maxi- I 100% Burn-in in Thermal Overload mum of 1 1%, allowing an overall power supply toler- ance to be better than 3% using inexpensive 1% resistors. Line and load regulation performance has been improved as well.

An LT317A and an LM317 from Linear Technology are side by side in this datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/lt0117.pdf The LT317A is indeed more accurate and has better line and thermal regulation (and may need one diode less to protect it if the input voltage should drop quickly, which it can't do ...
