The S-1167B40-I6T2U is a linear voltage regulator designed specifically for high current applications. It is designed to act as a interface between the supply voltage source and the load in a distributed power system. The device has two main functions: to provide a regulated voltage to the load and to provide current protection features.

The S-1167B40-I6T2U can operate in three different modes, depending on the application: Normal Mode, Low Drop-Out (LDO) Mode, and Fixed Output (FO). In Normal Mode, the device functions as a three terminal voltage regulator, with a programmable voltage supply range. The output voltage is set by an external resistor divider. The output current is limited to a set value, which is internally adjustable. The device has current express protection, which limits the output current over-short duration, when the load current exceeds the set limit.

In LDO Mode, the device\'s output voltage is adjusted by an external resistive divider to provide low current operating with low drop-out conditions. The device also includes a programmable thermal shutdown, allowing the device to protect itself in cases of high ambient temperature or high load currents. In this mode, the device\'s output current is also limited, once again by an adjustable internal limit.

Finally, the device\'s Fixed Output (FO) mode provides a constant voltage output, which can be adjusted to a certain level depending on the external resistive divider. This mode is suitable for applications requiring extra-low output noise and low temperature coefficient. In FO mode, the maximum output current is the same as in other modes, with the main difference being that it is adjustable via the external resistive divider.

The S-1167B40-I6T2U voltage regulator is ideal for use in applications with low standby current and high output current. It is suitable for distributed power systems where current regulation and protection is desired, and it is well-suited for automotive, consumer, and industrial applications. The device can also be used in battery-powered application or systems, as the current limit feature keeps the load current from exceeding levels which could damage the power supply.
