TL750L12CD

TL750L12CD is a high-performance linear regulator IC which is made specifically to be used as an adjustable low dropout (LDO) regulator. It can be used in electronics circuits with a wide variety of voltage requirements. Its rated input voltage range is 3V to 15V and its output voltage range is 1.2V to 12.6V. The maximum quiescent current is 8mA. This IC can also operate in higher voltage and current environments with some additional features included.

TL750L12CD is typically used in applications that require a low-noise and low-dropout linear regulator. These may include the following:

• Power supplies
• Consumer electronics
• Test and measurement equipment
• Communication hardware
• IP cameras

TL750L12CD works on a linear voltage regulator principle. This means that it converts a higher input voltage to a more precise lower output voltage, by utilizing an active internal circuit. This results in a very precise and stable output voltage, even under varying load conditions. The IC also provides some additional features such as a high power supply rejection ratio, a low quiescent current, and low noise performance.

The overall working of the TL750L12CD can be broken down into three main stages:

• Regulation
• Compensation
• Output load fixed

The linear regulator is composed of two essential components: an operational amplifier (op amp) and a pass transistor. The operational amplifier acts as a negative feedback loop which compares the reference voltage to the output voltage. This will then selectively pass a current through the transistor, to keep the output voltage stable.

The compensation element of the IC is responsible for providing stability to the circuit. The compensation element is composed of an evolutionary capacitor and a resistor. The capacitor and the resistor together will create a pole in the frequency response. This pole helps to minimize any overshoot or undershoot of the output voltage.

In order to provide a certain level of stability, the output load is connected to the pass transistor via the output load fixed pin. The output load fixed pin is responsible for helping to determine the output capacity of the LDO and providing constant current load. This helps to limit any excessive load on the pass transistor from the output load.
