The REG113EA-3/2K5 voltage regulator is part of the Linear product portfolio developed by Texas Instruments (TI). It belongs to the family of low dropout (LDO) voltage regulators, which are a type of PMIC (power management integrated circuits). These devices are important for efficient power supply designs, given their ability to provide a low-noise output voltage from a wide range of input voltage sources.

The REG113EA-3/2K5 has an adjustable output voltage (VOUT) and is able to accommodate both line and load conditions to ensure high levels of circuit performance. It provides an adjustability range starting from 1.5V to 7V, and has a maximum output current rating of 5A. The device also offers a typical line rejection of 55dB and a peak load transient of 25A, making it suitable for a wide variety of applications requiring an adjustable LDO regulator.

The REG113EA-3/2K5 is commonly used in applications where an adjustable output voltage is required, such as in embedded systems, telecommunications, power management, and consumer electronics. It is also suitable for automotive and industrial systems where the output voltage needs to be carefully controlled. Other applications for this device include medical equipment, wireless systems, LED lighting, and battery charging.

The working principle of the REG113EA-3/2K5 incorporates a three-terminal adjustable regulator that operates by employing a feedback network between the output node and an internal reference voltage (Vref). The regulator draws a current from the input voltage, VIN, and draws the same current from the output voltage, VOUT. When the voltage at the output node is lower than the reference voltage, the internal circuitry of the regulator turns on the output section and consequently increases the output voltage until it matches the reference voltage.

The REG113EA-3/2K5 is an efficient and reliable solution for applications that require an adjustable LDO regulator, offering superior performance and system flexibility. Its wide operating temperature range, low dropout voltage, high power capability, and adjustable output voltage make it an ideal choice for power supply design engineers.
