TC1173-3.3VUATR is an integrated circuit designed to provide linear voltage regulation. It provides a regulated output voltage of 3.3V, within a wide range of voltage inputs and load conditions. The circuit has high power efficiency, as well as short-circuit and over-temperature protection.

The TC1173-3.3VUATR is most commonly used in the power industry, providing a regulated supply to power microprocessors, FPGAs and ASICs. It can be used in cellular base stations, cloud computing platforms, medical electronics, industrial automation and many other applications. It is also suitable for automotive applications, with the operating temperature range of -40°C to 125°C.

The device is Pin-Compatible with low-voltage linear regulator (LDO) solutions, and is available in SOT-23-5 or SOT-223-5 packages. It features a very low quiescent current of 3.2mA, making it ideal for portable device applications.

The TC1173-3.3VUATR is designed to maintain a stable output voltage despite changes in the input voltage and load current. The output voltage is determined by a feedback loop and error amplifier which compares the output voltage of the regulator to an internal reference voltage. The output voltage is adjusted through a power transistor, which increases or decreases the load current determined by the error amplifier.

The device features voltage linearity error of 10mV, temperature coefficient of 0.1mV/°C and short-circuit current limiting of 6A. It also provides thermal shutdown protection, which will turn off the device if the temperature exceeds 150°C. The output requires no external component to maintain regulation.

The TC1173-3.3VUATR provides a cost-effective, compact, and efficient solution for applications requiring a low-voltage power supply. It is ideal for applications that require low noise, low ripple, and short-circuit protection. This device is perfect for providing power to embedded systems, automotive electronics and other high-precision electronics.
