PMIC (Power Management ICs) are a category of integrated circuits (ICs) which manage the power and the electrical conditions of an electronic application. Voltage regulators are one of the main components of a PMIC, as they manage the output voltage of an electronic system. REG113EA-3/250 is a simple adjustable low-dropout (LDO) voltage regulator that can adjust the input voltage to match the output voltage within a certain range.
The output voltage can range from 2.85V to 10V, and the dropout voltage is 0.9V typical. The REG113EA-3/250 operates over an input voltage range of up to 35V, and provides up to 250mA of output current. The device is designed with a safety margin to ensure safe operation of the system. The IC also incorporates short-circuit protection and thermal-overload protection.
Applications and Working Principle
The REG113EA-3/250 is a versatile device and can be used in a wide variety of applications that require a variable output voltage. The device is often used in consumer electronics applications such as portable devices, mobile phones, notebooks, and medical systems. It is also used in automotive applications such as drive systems, and applications require battery-backed power, such as alarms and uninterruptible power supplies (UPS).
The REG113EA-3/250 operates on the principle of low dropout voltage regulation. A low output-voltage differential (also known as \'dropout voltage\') ensures that the voltage at the output pin is kept close to the voltage at the input pin, even under light loads. This is accomplished by constantly regulating the output voltage pressure with respect to the input voltage.
The device operates in three modes: constant voltage mode, current steering mode, and sequential current steering mode. In constant voltage mode, the output voltage is maintained at its set value regardless of input voltage or current changes. In current steering mode, the output voltage is regulated to its set value by detecting current changes and actively switching elements to keep it within the specified range. Sequential current steering switches between constant voltage and current steering mode to ensure the output remains within the specified limits even when the current steps up and down.
The REG113EA-3/250 can be used as a direct replacement for older linear regulators, but it does not require the use of output capacitors, as the dropout voltage is too low for them to be necessary. This eliminates the need for additional components in the circuit, reducing size and cost.
The REG113EA-3/250 is a versatile, low-dropout voltage regulator that can be used in a wide variety of applications. With its integrated protection features and wide input and output ranges, the REG113EA-3/250 is the perfect choice for low-power and portable designs.
