Working Principle

MCP1825S-5002E/DB is a linear regulator that uses a voltage reference to regulate the output voltage. When the input voltage is higher than the reference voltage, the regulators linearizes one of the transistor\'s by passing current through it. This current reduces the differential between the actual output voltage and the reference voltage. When the temperature rises and the voltage drops, a comparable current is generated to maintain the output voltage.

To begin the regulation, the internal reference voltage on the regulator is compared with the output voltage via the error amplifier. If the feedback voltage is higher than the reference voltage, the error amplifier work as a differential voltage comparator, setting the power stage enter into linear operation. In this operation, current from the input is controlled to travel through the power switch, thus regulating the output voltage.

Conclusion

In conclusion, MCP1825S-5002E/DB is a low dropout, linear voltage regulator designed to provide an accurate voltage regulation in battery-powered applications. The relatively wide input voltage range, low power consumption and excellent load transient performance make it an ideal choice for applications that require precise and efficient regulation.
