Voltage regulators are a critical component in almost all modern electrical systems. Linear regulators are the most commonly used type because they offer low cost, low power consumption and a broad range of features and advantages. The TCR2DG18,LF series of linear voltage regulators from Texas Instruments are designed to provide reliable and adjustable output power, even in challenging applications. Let’s take a closer look at their application field and working principle.
Application Field
The TCR2DG18,LF series is designed to provide adjustable output power in a range of applications including automotive systems, consumer electronics, and lighting circuits. The device can be used to supply power to DC/DC converters, voltagecontrolled oscillator (VCO) and switching regulators. It features low dropout voltage, high output current range, and low quiescent current, making it suitable for applications requiring a variable output voltage. The TCR2DG18,LF also includes several features that make it ideal for automotive applications, such as temperature compensation, over-voltage and reverse-battery protection.
Working Principle
The TCR2DG18,LF is a linear voltage regulator that uses an externally adjustable voltage reference (Vref) to control the output voltage. The output voltage (Vout) is determined by the following equation:
Vout = Vref x (1 + (R1/R2)).
Where Vref is the reference voltage, R1 and R2 are the external resistors chosen to set the output voltage. The TCR2DG18,LF includes an integrated error amplifier, which ensures a stable output voltage by regulating the Vref setting. The output voltage is adjustable over a very wide range, from 0.2 V to 5.5 V.
The TCR2DG18,LF features low dropout voltage, which improves efficiency by reducing power dissipation and allowing the regulator to remain in regulation at lower input voltages. It also includes several protection features including over-current, over-voltage, reverse-battery and thermal protection. The TCR2DG18,LF has an operating temperature range of -40°C to +170°C and a quiescent current of 8.7 μA.
Conclusion
Texas Instruments\' TCR2DG18,LF linear voltage regulator offers many advantages for a variety of applications. It is designed to provide adjustable output power in automotive, consumer and lighting applications. The device features a low dropout voltage, high output current range and low quiescent current. It also includes several protection features to ensure reliable performance and long-term reliability. Its wide operating temperature range and low power consumption makes it an ideal choice for many applications.
