Working Principle

The S-1131B36PD-N4VTFG is a 2-channel linear regulator with a fixed output voltage. The design allows the device to work from a wide range of input sources. It is designed using a voltage reference to maintain the correct output voltage. An operational amplifier compares the output voltage with the reference voltage and adjusts the control signal to the linear circuit as necessary to maintain the desired output voltage.The output voltage is determined by two components, the external resistor divider connected to the output, and the internal reference voltage. The output voltage can be adjusted by changing the resistance of the resistor divider connected to the output.The linear regulator will not heat up unless the current limit is exceeded. The S-1131B36PD-N4VTFG can provide up to 3A of output current and maximum load of up to 36V. It also offers short-circuit protection, current-limit protection, and thermal-shutdown protection.

Conclusion

The S-1131B36PD-N4VTFG is a two-channel linear voltage regulator suitable for various applications that require regulated DC output voltage in a small form factor. This device is designed to work with a wide range of input voltages and provides protection from thermal shutdown, over current, and short-circuit protections. This device is an ideal solution for applications where space and cost are limiting factors.
