LM317低压差(LDO)线性稳压器是一款可调3端正向LDO稳压器,能够在1.2V至37V的输出电压范围内提供1.5A以上的电流。这款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,它提供内部电流限制、高温关断和安全区域补偿,真正实现防爆性能。
LM317适用于多种应用,包括局部、片上调节。这款器件还可用于制造可编程输出稳压器,或通过在调节和输出之间联接一个固定电阻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.)
