概览

LM317M 是一款可调三端子正向线性稳压器，能够在 1.2 V 至 37 V 的输出电压范围内提供 500 mA 以上的电流。此线性电压稳压器使用非常简便，仅需两个外部电阻即可设置输出电压。另外，它采用内部电流限制、高温关断和安全区域补偿，使其能够实现真正的抗撞击。LM317M 适用于多种应用，包括局部、卡上调节。此线性稳压器还可制成一个非常简单的可调节开关稳压器、可编程输出稳压器，通过在调节和输出之间联接一个固定电阻，LM317M 还可以用作精确电流稳压器。

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
