S-1701F3025-M5T1G Application Field and Working Principle
The S-1701F3025-M5T1G is a micro-capable negative voltage regulator. It is a three-terminal device that provides negative output from positive power sources. Unlike ordinary fixed regulators, the S-1701F3025-M5T1G voltage regulator is completely adjustable over a wide range of voltage and current outputs. This makes it ideal for applications that require adjustment of output voltages in the range of -1.5V to -6V.
The S-1701F3025-M5T1G is commonly used in applications such as automotive electronics, security systems, mobile communications, and lighting control systems. It is also used in any system requiring a negative voltage supply, such as TVs, computers, and other electronic devices.
The S-1701F3025-M5T1G is typically supplied in a TO-220 form factor. Its internal circuitry is designed to conserve power and space. The device consists of two main components, the control circuit and the main regulator circuit.
Control Circuit
The control circuit is most important in the S-1701F3025-M5T1G voltage regulator. This circuit contains a low-voltage sensing network with hysteresis protection and a base-drive circuit. The low-voltage sensing network senses the output voltage and sends a signal to the base-drive circuit to turn on the main regulator circuit when the output falls below a predetermined level. At the same time, the hysteresis protection configuration helps to protect against false triggering of the device. The hysteresis protection can also reduce power consumption by preventing the regulator from constantly turning on and off.
Main Regulator Circuit
The main regulator circuit contains a two-stage bipolar transistor that provides a fixed negative voltage output. The two-stage circuit acts as a current source, with the current and the voltage corresponding to the voltage at the base. The main regulator circuit also contains an enable/disable pin, which when active will enable the main regulator circuit and allow it to deliver its negative voltage output.
The S-1701F3025-M5T1G is designed to provide high accuracy and reliability, allowing it to maintain a constant output voltage even when faced with varying line and load conditions. The device can withstand a reverse input voltage of up to 20V and is tolerant to high temperatures, up to 125°C.
The S-1701F3025-M5T1G is an ideal solution for applications that require adjustable negative voltage outputs over a wide range. Its small size and integrated complexity make it an ideal choice for a variety of systems.
