PMIC - Voltage Regulators - Linear

The S-1170B33PD-OTSTFG is a linear voltage regulator PMIC (power management IC) installed in a small, ultra-low power 28-pin QFN package, making it a particularly suitable choice for a wide range of voltage regulation applications, from microcontrollers to smartphones, tablets and embedded devices. Its features include a wide input voltage range from 5V down to 1.5V and a wide output voltage range from 0.8V to 5.5V. It also has a low quiescent current and strong protection functions. These features make this device one of the best choices for advanced and versatile power restraining solutions.

Application Field

The S-1170B33PD-OTSTFG is a highly integrated linear voltage regulator PMIC, making it a great choice for applications where a wider input voltage and output voltage range, or higher efficiency power supply, is needed – such as portable devices, sensors, and microcontrollers. It allows the design of power supplies with both sub 1V and other interfaces while keeping a low quiescent current, reducing power consumption and increasing battery life. These are critical considerations since designers are often up against energy, space, cost and performance requirements, in addition to stringent safety standards. The device is suitable for automotive industry, medical electronics, industrial low power application, and wearable electronics.

Working Principle

A typical linear regulator circuit consists of three main components: an input voltage source, a pass transistor, and an output capacitor. The input voltage comes from either an external power supply, or a battery. The pass transistor is in series with the input voltage. The output capacitor stores charge and provides a consistent and regulated output voltage to the load. The output voltage remains constant and unaffected by changes in input voltage or load current. When the load current exceeds the maximum capacity of the pass transistor, it switches off and the output voltage will be reduced to the level of the input voltage. The S-1170B33PD-OTSTFG is powered by N-channel MOSFETs to provide stable output voltage, current and power over a wide range of input voltages. It offers superior immunity to input transients and switches off the MOSFETs when the input voltage is above or below the operating range. The device also offers built-in overload protection, overvoltage protection and overtemperature protection. Moreover, it features advanced features such as smart shutdown, adjustable output voltage and overcurrent protection.

Conclusion

The S-1170B33PD-OTSTFG is a versatile and robust linear voltage regulator PMIC that can handle a wide range of voltage regulation applications in portable devices, sensors, and microcontrollers. It features a wide input and output voltage range, low quiescent current, and advanced protection features.
