S-1170B19PD-OTETFG

Introduction

The S-1170B19PD-OTETFG is a component in the integrated circuit (IC) of a linear voltage regulator–commonly used in a Power Management IC (PMIC) system. This component is designed to stabilize the output voltage and adjust its output value under a wide range of conditions. It consists of an integrated circuit (IC), an external feedback circuit, and an output capacitor.

Working Principle

A linear voltage regulator uses an operational amplifier (op-amp) to adjust the reference voltage of the output current. This reference voltage is used as the input to the op-amp and is compared to the feedback voltage coming from an external resistor network.

The op-amp compares these two voltages and generates a signal that is sent to an output transistor, which modulates the output voltage. The S-1170B19PD-OTETFG contains a voltage output stage, a current detection stage and other circuit elements to produce a linear relationship between the reference voltage and the output current.

In a linear voltage regulator, the output voltage is held constant by changing the voltage of the input signal which is supplied to the transistor. This allows the system to regulate the output current and voltage as the load changes – and maintains a constant output voltage - even if the load and environment conditions change.

Application Field

The S-1170B19PD-OTETFG is suitable for a wide range of applications, including portable devices such as mobile phones, digital cameras and portable media players. It is also suitable for use in consumer electronics and industrial applications such as air conditioners, refrigerators and printers.

The S-1170B19PD-OTETFG operates from a voltage range of 1.5V to 18V, providing three distinct output voltages which are regulated over a certain temperature range. It also has a wide operating frequency range of 1kHz to 200kHz, allowing for efficient and stable operation in any application.

This component also features an input current limit of 1A, switching times of 100ns, under voltage lockout and thermal shutdown protection. It is also compliant with the RoHS and WEEE standards, making it safe to use in consumer products.

Conclusion

The S-1170B19PD-OTETFG is an excellent choice of linear voltage regulator for applications in consumer and industrial devices. It is designed to provide stable output voltage and current over a wide range of conditions and can operate at a variety of frequencies and temperatures. Furthermore, it is compliant with the RoHS and WEEE standards, making it a safe and reliable choice for any application.
