TCR15AG09,LF application field and working principle

TCR15AG09,LF is a device of power management integrated circuit (PMIC) , specifically under the category of voltage regulators –linear. This device is a low drop out (LDO) voltage regulator and provides output voltage of 1.8V to 5.5V. It is able to operate at temperatures ranging from -40℃ to 125℃ and its output current can reach 800mA, making it suitable for many types of applications. The application field are mainly divided into consumer electronics, automotive electronics and computing equipment and so on.

Working Principle of TCR15AG09,LF

TCR15AG09,LF is based on a PMOS pass transistor technology, with a negative feedback loop to control the output. The Major feature of TCR15AG09,LF is low dropout voltage. This helps to ensure that the voltage regulation is more precise and the electrical performance is more stable. Another important feature is its temperature performance which is better than most other PMICs. The working principle of TCR15AG09,LF is basically the same as other linear voltage regulators. The input voltage is regulated by the pass transistor (PMOS) to provide the proper output voltage. The feedback loop has a voltage reference source, a voltage divider, transconductance (Gm) amplifier and error amplifier (OPAMP) connected in a circuit, to maintain the output at a given level of accuracy. The Gm amplifies the difference between the reference output and actual output, which is then feed to the error amplifier to adjust the gate voltage of the PMOS. This, in turn, corrects the output voltage and thus the output voltage is regulated. The TCR15AG09,LF can be connected in many different configurations. It is normally used in an adjustable voltage configuration, where the output voltage can be adjusted using an external divider, or it can be connected to an external reference like a zener diode. It can also be used in a fixed voltage configuration. In addition, this regulator is also equipped with several protection functions such as over-voltage, over-current, and short-circuit protection. These protect the device from any kind of uncontrolled current situation.
