S-1335F35-A4T2U3

Introduction

Integrated circuit (IC) technology has become increasingly important in recent years with more and more to apps emerging and developed to meet user needs. ICs offer a wide array of features and functions, from simple voltage/current regulation to complex integrated circuit designs. The S-1335F35-A4T2U3 is an example of a high-performance voltage regulator by a well-known IC manufacturer.

Application Field and Working Principle

The S-1335F35-A4T2U3 is a negative voltage regulator that provides a regulated negative output voltage of 5.0V and a maximum output current of 1.5A. It is intended for use in applications such as servers, routers, and personal computers, where high power and a regulated negative supply voltage are required. The device incorporates several innovative features, including low voltage drop performance, low-noise output, and line compensation for superior dynamic response.

The S-1335F35-A4T2U3 is a linear voltage regulator, which is based on the principle of effecting current control to regulate the output voltage. It works by regulating the output voltage of the device using two internal reference voltages, an output current setting resistor, and an error amplifier. The error amplifier compares the output voltage to an internal reference voltage, and adjusts the output current to the load until the output voltage matches the reference voltage. The output current setting resistor sets the output current limits.

The S-1335F35-A4T2U3 is equipped with over-current protection, short circuit protection, thermal protection and reverse-voltage protection. The over-current protection is triggered when the output current exceeds the set limit, and will shut down the regulator to protect it from damage. The short-circuit protection is triggered when a short circuit occurs across the output. It will shut down the device to protect from damage due to excessive current draw. The thermal protection prevents overheating by shutting down the regulator if the internal temperature exceeds a certain limit. The reverse-voltage protection shuts down the device if the input voltage is reversed.

Features

The S-1335F35-A4T2U3 offers several outstanding features, including:

• Low voltage drop performance - low voltage drop across the regulator is essential for maximizing system efficiency.
• Low-noise output - the low-noise output allows for smooth power delivery while minimizing noise.
• Line compensation - this feature compensates for line losses across the supply lines and helps maintain stable output voltage.
• Over-current, short circuit, thermal, and reverse-voltage protections - protects the device from damage due to excessive current draw or reversed input voltage.

Conclusion

The S-1335F35-A4T2U3 is a high performance linear voltage regulator intended for use in applications such as servers and routers, where high power and a regulated negative output voltage are required. It combines several innovative features, including low voltage drop performance, low-noise output, and line compensation, along with over-current, short circuit, thermal, and reverse-voltage protections. These features make the S-1335F35-A4T2U3 an ideal solution for voltage regulation in high power applications.
