S-1167B27-I6T2G Application Field and Working Principle

The S-1167B27-I6T2G is an IC package consisting of a linear voltage regulator (LVR). It provides precise output voltage regulation and is designed to work over a wide input voltage range. The LVR can also provide current limiting and initial start-up inrush current limiting when the input voltage is in the operating range. It also offers low noise, high precision output voltage regulation and excellent power supply rejection.

The S-1167B27-I6T2G is typically used in applications such as adjustable voltage power supplies, flexible power supplies, portable power systems, DC-DC converters, low-voltage solar and automotive applications. It is also used in various other power supply applications such as back-plane or auxiliary power supplies, low noise level medical and instrumentation applications, low noise communication systems, and non-isolated DC-DC converter and telecom applications.

Working Principle

The voltage regulator works by controlling the current drawn from an input power source, such as a battery or generator, and provides a regulated output voltage. The S-1167B27-I6T2G provides excellent transitional testing and stable output voltage accuracy. It consists of a feedback loop that compares the actual input voltage (Vpas) with the desired output voltage (Vref). When the actual voltage differs from the reference voltage, the LVR adjusts the current draw from the input power source to maintain the desired output voltage.

The output voltage of the S-1167B27-I6T2G is typically adjustable by means of a multivibrator. The voltage is regulated using an internal voltage source and comparing the two to the reference voltage. This is a useful feature when the output voltage needs to be adjusted according to the application where it is used. The output voltage can be adjusted within the input voltage rating range.

The S-1167B27-I6T2G also offers overload and short-circuit protection. In the event of overload conditions, the output voltage will be reduced to a safe level and the output current will be limited to the preset value. In the event of a short-circuit, the output will be shut off for a predetermined period of time until the fault is cleared.

The S-1167B27-I6T2G has excellent stability over the entire input voltage range and is able to provide precision output voltage regulation with high efficiency. It is ideal for low current and battery applications that require a high level of accuracy, while still providing no external components.
