It can be used as a voltage regulator in power supplies and other power related circuits. It is also suitable for current limited applications, such as USB and cable modem supplies, shared voltage systems, power modules, and power conditioning.The S-1335D18-A4T2U3 is especially suited for applications with slow changing load, such as machine tools and industrial systems. It is also suitable for low voltage applications, like internet access or remote equipment.

Features of S-1335D18-A4T2U3

The S-1335D18-A4T2U3 has many features that make it a suitable choice for a wide range of applications. It has a wide operating temperature range (-40 to +85°C), low temperature coefficient (3.5mV/°C) for high accuracy and stability, low dropout voltage (0.5V max), and a high switching frequency (500kHz).The S-1335D18-A4T2U3 also has very low quiescent current (1mA max), which can be beneficial in low power applications. It also has adjustable output voltage and current limit settings, allowing for flexibility in design. The S-1335D18-A4T2U3 is RoHS compliant, and has a very small package size (3.3 x 2.5mm).

Working Principle of S-1335D18-A4T2U3

The S-1335D18-A4T2U3 is a low dropout (LDO) linear regulator. It operates on the principle of a foldback current limit circuit. The output is regulated to a certain voltage (the “set point”) by passing a fixed current through an external resistor connected between the adjustment pin and ground. This current must be kept constant for the output voltage to remain constant.When the output voltage exceeds the set point, the S-1335D18-A4T2U3 senses this and ramps down the regulated current to maintain the set point. The foldback current limit circuit also prevents a high inrush current from occurring when the output voltage is initially very low. This helps to protect the device from inrush current, and also helps to reduce output voltage ripple.

Conclusion

The S-1335D18-A4T2U3 is a low dropout linear regulator, designed to meet a wide range of applications. It is suitable for industrial, medical and consumer applications, and has a wide range of features that make it a suitable choice. It has good temperature coefficient stability, low dropout voltage, high switching frequency, low quiescent current, adjustable output voltage and current limit settings, and is RoHS compliant. The working principle of the S-1335D18-A4T2U3 is based on a foldback current limit circuit, where the output voltage is regulated to a certain point by passing a fixed current through an external resistor.
