TC1107-2.7VUA is a linear voltage regulator from Infineon Technologies. By using a single external voltage divider, the voltage regulator adjusts the external voltage to its specified regulated output voltage, making it suitable for a wide range of applications in industrial and automotive systems. This article provides an overview of the linear voltage regulator\'s application fields and working principle.

Application Fields

The TC1107-2.7VUA covers a wide range of system voltage requirements, such as those found in automotive, industrial and telecommunication systems. It is commonly used to power on-board voltage regulators, audio equipment, regenerative braking systems, etc. Additionally, the device provides a wide input voltage range, low noise and low quiescent current necessary for applications where efficiency is extremely important, such as in battery-powered systems.

Working Principle

At its most basic level, the TC1107-2.7VUA works by using an external voltage divider that adjusts the input voltage to the regulator’s specified regulated output voltage. The voltage regulator supports a wide range of input and output voltage ratios, from 0.5V to 6V, making it suitable for a variety of applications. An internal switch is used to select the maximum output current, which is typically between 0.3A and 1A.

The voltage regulator also incorporates over-voltage protection, a feature needed to protect the downstream circuits when the input voltage exceeds the recommended levels. When over-voltage protection is enabled, the voltage regulator reduces its output voltage to the maximum safe value, protecting the downstream circuits from any potential damage.

The linear voltage regulator also supports an Enable pin that allows the user to manually control the device’s operation. This feature can be used to save energy in applications that require frequent power-up/power-down sequences.

Conclusion

TC1107-2.7VUA is a linear voltage regulator from Infineon Technologies that is suitable for a wide range of automotive, industrial and telecommunication systems due to its wide input and output voltage range, low noise and low quiescent current. The device also includes an Enable pin for manual control of the device’s operation. Additionally, the voltage regulator includes over-voltage protection for added safety.
