Working Principle

S-11L10A11-M5T1U operates by sensing a voltage across a voltage reference network, which generally consists of an internally trimmed band gap voltage reference and a resistor divider. The regulation (output voltage adjustment) is accomplished by comparing the output voltage to the reference voltage and making adjustments to a series pass device such as an NPN bipolar transistor to correct for any discrepancy between the set point and the measured voltage.The output voltage is regulated to the voltage reference level by controlling the base drive to the pass device. The reference network is usually designed so that the regulator can be adjusted over several volts. Rather than using a trimming network, the output voltage of the regulator can also be set by supplying a greater voltages to the reference divider (known as the Adjust Pin).

Conclusion

The S-11L10A11-M5T1U is a 3-terminal negative adjustable linear voltage regulator from M22L1 series from STMicroelectronics. It is widely suitable for applications of negative voltage regulation and operates by sensing a voltage across a voltage reference network.
