LM317慢速开启 15V 稳压器的典型应用。 LM217、LM317 是采用 TO-220、TO-220FP 和 D2PAK 封装的单片集成电路，旨在用作正向可调稳压器。它们设计用于提供超过 1.5 A 的负载电流，输出电压可在 1.2 至 37 V 范围内调节。标称输出电压通过电阻分压器进行选择，使该器件非常 ...

放大板子上有了电解电容，为了补偿一下高频特性，我在电源板子上装的是固态电容 放大板要修改后才能与各位见面，虽然能用，但乱七八糟一通，不忍直视 采用经典可靠的LM317+LM337万金油方案，10cm*10cm(100mm*100mm)的小巧体型，还板载变压器和EMI，比过市面上绝 ...

First, you probably should move to the high voltage version of the LM317 which can handle up to 60V. This will give you design margin to protect your design from spurious transients and tolerances.

For example if the target output voltage is 10V then the R2 value is calculated as following: So this is how we calculate the R2 and output voltage for LM317 voltage regulator circuit. This LM317 ...

Thank you. Are you asking if LM317 can be a voltage regulator and a current limiter (other than internal current limit) at the same time? No it can not. There are way to implement this in some cases.

ESR of C2 is 100mOhms Adding an output capacitor, C2, effectively bypasses the regulator at higher frequencies. As the LM317 is inductive in these regions, this makes for a resonant circuit and hence ...

Set an LM317 circuit up to output 10mA, say, and you can safely test out about any LED. Read off the operating voltage, subtract that from the supply voltage, and then divide by your desired ...

The above schematic comprises almost anything you can put around the ubiquitous LM317 positive 3-pin regulator (LM337 for negative voltages, 117 and 137 military versions). The basic circuit dispenses ...
