The TC2185-1.8VCTTR is an adjustable linear voltage regulator that operates with a wide range of input voltages up to 12 V.This device is useful for providing a low-noise, low-ripple voltage supply for many applications, such as embedded microprocessors, analog circuitry and high-precision analog to digital converters.The TC2185-1.8VCTTR has a low quiescent current, high power output and low voltage dropout which make it ideal for powering small low-noise circuits in applications with limited power sources and/or limited space.

The TC2185-1.8VCTTR is a compact adjustable voltage regulator that uses a reference voltage derived from an external resistor divider to set its output.The device has a wide operating range of 8 V to 12 V and can deliver up to 100 mA of output current. The output voltage of the device is adjustable from 0.9 V to 2.8 V. A single resistor can be used to set the output voltage from 0.9 V to 1.8 V and a second resistor is used to set the output voltage from 1.8 V to 2.8 V.

Application Field:

The device is ideal for low noise low power applications, like powering microprocessors, analog circuits and A/D converters. It’s suitable for small space and limited power supply circuits, where power output and low quiescent current is needed.

Working Principle:

The TC2185-1.8VCTTR uses a resistor-based method to set the output voltage. Firstly, a voltage divider consisting of two external resistors is used to generate a reference voltage. This reference voltage is compared with an internal fixed reference voltage, where the difference between the two is used to determine the output current of the device and thus the output voltage. As the output voltage is regulated, any change in the input or load current is automatically compensated for, ensuring that the output voltage stays constant.

Conclusion:

The TC2185-1.8VCTTR is a versatile device for providing a low-noise, low-ripple output for many applications. It’s suitable for limited space applications with limited power sources and offers a wide input voltage and output voltage range. The adjustable nature of the device means that it can be used to provide a wide range of output voltages and is ideal for powering small low-noise circuits.
