The LM2931xx are very low drop regulators. The very low drop voltage and the low quiescent current make them particular suitable for low noise, low power applications and in batterypowered systems. In the 8-pin configuration (SO8), fully compatible with the older L78Lxx family, a shutdown logic control function is available. This means that when the device is used as a local regulator it is possible to put a part of the board in standby, decreasing total power consumption. Ideal for automotive applications, LM2931xx is protected from reverse battery installations or 2 battery jumps. During the transient, such as a 60 V load dump, when the Table 1. |
