BD70GC0WEFJ-E2 is an adjustable Linear Voltage Regulator integrated circuit (IC) available in TO-220 package manufactured by ROHM. The IC is specially designed for various voltage regulator applications like 12V power supply, adjustable power supply, non-critical applications, and battery chargers. In addition, the BD70GC0WEFJ-E2 is very popular in automotive and lighting applications due to its wide operating temperature range.
Basic Architecture
The BD70GC0WEFJ-E2 contains several integrated circuits, including an amplifier circuit, a voltage reference circuit, a current limit circuit, and an error amplifier circuit. The BD70GC0WEFJ-E2 is designed to operate over a wide input voltage range of 4.5-28V and can provide an adjustable output voltage from 0.8-20V. The device is also capable of delivering a maximum output current of 2A. Built-in protection features include over-voltage, over-current, and short-circuit protection.
Working Principle
The overall functionality of the BD70GC0WEFJ-E2 is based on the operation of an amplifier circuit, a voltage reference circuit, a current limit circuit and an error amplifier circuit. It uses an internal voltage reference to regulate the output voltage when the load current is drawn. The amplifier circuit amplifies the output voltage signal and the current limit circuit limits the output current. The error amplifier circuit compares the output signal to the reference signal of the voltage reference circuit and makes the necessary adjustments to keep the output voltage within the specified range.
Application Field
The BD70GC0WEFJ-E2 is a great choice for applications that require a stable and reliable output voltage, such as 12V power supplies, adjustable power supplies, non-critical applications and battery chargers. It can also be used in applications where it is necessary to reduce output ripple and prevent spikes in the output voltage. Furthermore, the BD70GC0WEFJ-E2 is ideal for automotive and lighting applications due to its wide operating temperature range. The IC also provides protection against over-voltage, over-current, and short-circuit making it suitable for use in harsh environments.
