AP7343D-28FS4-7B

AP7343D-28FS4-7B is a linear voltage regulator used in power management applications. It is able to support input voltages of up to 28 V, and can output an adjustable voltage of up to 7.3 V. It is manufactured by the Taiwan Semiconductor Corporation, and is available in a small, surface-mount SOT-23 package. The AP7343D-28FS4-7B is designed to control the output voltage of a circuit with a minimum of external parts, making it ideal for a variety of specialized and general-purpose applications.

The AP7343D-28FS4-7B is an adjustable three-terminal voltage regulator that utilizes an input voltage of up to 28 V. The device can provide an adjustable regulated output voltage of up to 7.3 V with a resistive divider or external reference voltage. The AP7343D-28FS4-7B can provide an output current of up to 300 mA, or up to 2 A with the addition of an external pass transistor. The device is a trimmable regulator, which allows the user to adjust its output voltage level over the full range of its input voltage.

The AP7343D-28FS4-7B is designed for low-dropout operation. This means that the output voltage of the device can stay within a few volts of its input voltage even as the input voltage decreases. As the input voltage gets closer to the output voltage, the AP7343D-28FS4-7B automatically reduces the output current to prevent excessive current from flowing through the device. Additionally, the device has an over-temperature and over-current protection feature that protects it from damage in the event of a fault.

There are a variety of applications for the AP7343D-28FS4-7B, including applications in automotive and industrial electronics, telecommunications, medical and instrumentation systems, and computer systems. The AP7343D-28FS4-7B is used to provide a regulated voltage output for voltage-sensitive components, such as microcontrollers, EEPROMs, and other digital logic circuits. Additionally, the device is suitable for powering ICs, display systems, and battery chargers.

The AP7343D-28FS4-7B operates through linear regulation, which is a method of maintaining a constant output voltage by varying the current draw from the input voltage source. The AP7343D-28FS4-7B utilizes an internal feedback system to detect changes in the output voltage from the desired setting. If the output voltage changes, the device will adjust its current draw from the input voltage source in order to maintain the desired output voltage. In addition, the device is equipped with an on-chip current limiting feature that monitors the output current and shuts off the output if the current limit is exceeded.

The AP7343D-28FS4-7B is designed to undergo a series of verification tests prior to shipment, including thermal testing and electrical parameter testing, to ensure that the device meets all specified performance requirements. Additionally, the device is available in an SOT-23 package, which has a low profile and allows for easy integration into a circuit board.

The AP7343D-28FS4-7B is an ideal linear voltage regulator for a variety of specialized and general-purpose applications. It is able to provide an adjustable regulated output voltage of up to 7.3 V with a resistive divider or external reference voltage. Additionally, the device has built-in current limiting and over-temperature protection features and is available in a small, surface-mount SOT-23 package.
