The LT6656BCS6-2.5#TRPBF can be used for systems that require very low voltage drift as it offers temperature stability of 0.005%/°C.

The LT6656BCS6-2.5#TRPBF is also ideal for precision-timing applications. It is available in a SOT-23 package and has very low quiescent current consumption of 1.1μA. This makes it suitable for battery-powered devices.

Working Principle

The LT6656BCS6-2.5#TRPBF operates on a bandgap principle. This involves creating a temperature-stable reference voltage by combining two different voltages generated by two different types of semiconductor devices. The LT6656BCS6-2.5#TRPBF has two inputs – a positive input and a negative input. The positive input receives a reference voltage, which is the voltage reference the device provides. The voltage reference is generated from the bandgap circuit.

The negative input of the LT6656BCS6-2.5#TRPBF is connected to the output of the device. This creates a voltage loop, where the output voltage is compared to the input voltage. If the voltage difference exceeds a certain value, the output voltage is adjusted to match the input voltage. This process is known as error amplification and it helps to improve the accuracy and stability of the output voltage.

The LT6656BCS6-2.5#TRPBF also has a provision for an external bias voltage. This can be used to adjust the output voltage of the device. The external bias voltage is applied to the positive input of the device.

Finally, the LT6656BCS6-2.5#TRPBF has a current limiting function. This helps to protect the device from exposure to large currents. It operates by automatically limiting the output current to a preset value if the current exceeds the preset value.

Conclusion

The LT6656BCS6-2.5#TRPBF is a high-precision, low-dropout voltage reference designed for low power applications. It is ideal for precision-timing and high-accuracy power management applications. The LT6656BCS6-2.5#TRPBF operates on a bandgap principle and offers temperature stability of 0.005%/°C. It also has an external bias voltage provision and a current limiting function for additional protection.
