Working Principle of S-1170B53UC-OUMTFG

The S-1170B53UC-OUMTFG is a two-terminal low-dropout (LDO) voltage regulator. The regulator operates by adjusting the output voltage to maintain a constant voltage drop between the input and output terminals. The output voltage of the regulator is determined by the ratio of two resistors, R1 and R2, connected between the ground and the REF terminal.When the voltage drop across the regulator is greater than the desired output voltage, the control circuit turns on the internal transistor M1 which limits the current passing through the regulator by decreasing the voltage drop across it. When the voltage drop across the regulator is lower than the desired output voltage, the control circuit turns off the internal transistor M1 which increases the current passing through the regulator and increases the voltage drop across it. The adjustability of the output voltage is achieved by changing the value of the two resistors, R1 and R2.The S-1170B53UC-OUMTFG voltage regulators also feature a low quiescent current of 1.3 μA and a fast transient response. It has an operating voltage range of 2.5 V – 5.5 V and can deliver up to 45 mA of output current, making it ideal for low-power applications.
