Working Principle

The S-1167B15-M5T1G linear voltage regulator works by regulating the input voltage to a predetermined output voltage. The input voltage goes through a voltage divider and is divided down before being passed through a temperature compensating circuit. The output is regulated by a variable resistor, which is adjusted with a reference voltage. The variable resistor adjusts the output voltage to maintain the desired accuracy. The output voltage is further regulated by an error amp, which is adjusted with a reference voltage. The error amp controls the output voltage to keep it within the specified accuracy range. The output voltage is then compared to the reference voltage and if there is any difference, an error voltage is generated to correct it. Finally, the output voltage is passed through a low dropout voltage regulator, which ensures that the output voltage is stable, regardless of the input voltage. This ensures that the voltage regulator is capable of providing precise voltage regulation. Furthermore, the low dropout voltage regulator also provides low quiescent current and improves the efficiency of the voltage regulator.

Conclusion

The S-1167B15-M5T1G is a precision linear PMIC voltage regulator. It is suitable for a wide range of applications and provides low dropout voltage and low quiescent current for excellent efficiency. In addition, the adjustable output voltage, adjustable current limit, over temperature protection and reverse voltage protection make it suitable for use in rugged applications.
