LM117/LM317A/LM317 three -terminal can be adjusted
General description
lm117 The series of adjustable three -terminal positive voltage regulator can be output range of 1.2V to 37V. They only need only two external resistors to set the output voltage. In addition, lines and load adjustments are better than standard fixed regulators. In addition, the packaging of LM117 is easy to install for the installation. In addition to higher performance than fixed regulators, the LM117 series provides full overload protection. It only includes current restrictions, heat overload protection and security areas on the chip. The circuit can still work normally even if the terminal is disconnected. Usually, no capacitors are required, unless the device needs to enter the bypass if the device is 6 inches above 6 inches. Optional output can add a capacitor to improve the transient response. This can bypass the adjustment terminal to achieve a ripple suppression ratio that is difficult to achieve with a very high value of the standard three -ends. In addition to replacing fixed regulators, LM117 is widely used in other applications. Because the regulators are floating " and only see the input output difference voltage
