Working Principle

The LT1761ES5-5#TRMPBF is a linear voltage regulator. It works by using a PNP transistor and series resistors to reduce the input voltage to the desired output voltage. The output voltage is set by the reference voltage (1.21V) and the series resistors connected to it. When the input voltage is higher than the reference voltage, the PNP transistor is turned on and the input voltage is dropped across the series resistors. This creates a voltage divider circuit which reduces the input voltage to the desired output voltage. When the input voltage is lower than the reference voltage, the PNP transistor is turned off and the output voltage equals the input voltage.

Conclusion

The LT1761ES5-5#TRMPBF is a low dropout linear voltage regulator from Linear Technology. Its wide input and output voltage ranges make it a versatile choice for powering low power, low current applications. It has an on-board bandgap reference for accurate regulation and a maximum output current of 90mA. The device is built using advanced CMOS process for superior performance.
