BD750L2EFJ-CE2 application field and working principle

The BD750L2EFJ-CE2 is a linear voltage regulator from Renesas Electronics Corporation, which is also known as the Super Miniature Saddle Type Regulator IC. This IC is an individually packaged and ideal for creating voltage outputs for monitoring circuits and stabilizing the power supply. It has a wide range of applications including cameras, PCs, game machines, digital home appliances, and measurement instruments.

The BD750L2EFJ-CE2 features an input voltage range of 10V to 25V, and an output voltage range of 5V to 18V, with a minimum voltage differential of 1.5V. It also has a maximum output current of 500mA and a total output power of 35W. The IC is also designed with a built-in overcurrent protection (OCP) feature, which prevents overcurrent conditions from damaging the regulator and connected circuits.

In terms of working principle, the BD750L2EFJ-CE2 uses a linear voltage regulator integrated circuit (IC). This type of regulator is designed to provide a stabilized and accurate output voltage from a power supply regardless of load, temperature, power supply voltage, and other similar factors. This is accomplished by using a series of fixed resistor and zener diode components in the regulator circuit.

The input voltage is applied to the resistor string via an enable pin, which creates a voltage divider comprising of several resistors and diodes connected in series. When the enable pin is low, the voltage is divided according to the total resistance of the resistor string. When the enable pin is high, the voltage is adjusted by the zener diode and reference voltage, resulting in a stabilized output voltage.

In a linear regulator IC, the voltage across the output current is dropped when the load current increases. This drop in voltage is known as the dropout voltage, and is dependent on the amount of current passing through the regulator IC. As the input voltage is usually higher than the output voltage, the dropout voltage tends to be minimal.

Generally, a linear regulator IC like the BD750L2EFJ-CE2 is a cost-effective and reliable solution for controlling the output voltage of a power supply. This makes it an ideal choice for many applications, particularly those that require a high degree of accuracy and reliability.
