S-1132B41-I6T2U

S-1132B41-I6T2U is a Linear Voltage Regulator (LVR) that belongs to the Power Management Integrated Circuit (PMIC), and it is used in various applications. In order to understand its application field and working principle, let\'s start with the basics.

What Is LVR?

Linear Voltage Regulators are a type of electronic component that works as a direct voltage power supply. It works by controlling the voltage across its output terminals. This component provides stable output voltage even when load or input voltage fluctuates. LVR’s are preferred in applications that require precise output voltage regulation. Typical applications of LVR are digital circuitry, audio amplifiers, microcontrollers, power supplies, and other electrical or electronic systems.

What Are the Benefits of Using LVR?

LVR provides numerous advantages to the user. This component is simple and inexpensive to install, easy to maintain and adjust, and highly adaptable for various power requirements. Additionally, it is highly resistant to temperature changes. Compared to switch mode voltage regulators, it does not produce high-frequency electromagnetic interference. Lastly, due to its low voltage and low power output, LVR can prove beneficial in systems with low power requirements.

What Does S-1132B41-I6T2U do?

S-1132B41-I6T2U is a low-input voltage, low-dropout linear regulator that is specifically designed to work in applications with input voltage ranging from 3 to 3.6V and output voltage of up to 3.3V. This LVR provides up to 1A output current with very low power consumption, hence it is suitable for low-power applications. Additionally, this LVR features low voltage-drop, high accuracy and improved power conversion efficiency. It has a built-in controlled-on-time PWM (pulse width modulation) mode for improved efficiency, which helps to reduce the overall power consumed during its operation.

S-1132B41-I6T2U Application Field and Working Principle

S-1132B41-I6T2U is mainly used in electronics and electrical systems where precise voltage regulation is required. It also provides excellent protection against over-temperature and over-current conditions. The working principle of this LVR is based on a basic voltage regulator circuit. Its integrated power switch utilizes pulse width modulation (PWM) control to regulate the output voltage. It works by comparing the feedback voltage with an internal reference voltage and adjusting the output current accordingly.

When the output voltage is higher than the internal reference voltage, the power switch turns off, thus reducing the output current. In contrast, when the output voltage is lower than the internal reference voltage, the power switch turns on, which increases the output current, thus maintaining a constant output voltage. The feedback voltage is generated by the output of the LVR, thus forming a closed-loop feedback circuit.

Conclusion

S-1132B41-I6T2U is a low-input voltage, low-dropout linear regulator from the Power Management Integrated Circuit family. It is suitable for applications with low power requirements, such as digital circuitry, audio amplifiers, microcontrollers, and power supplies. Its working principle is based on a basic voltage regulator circuit, which utilizes a pulse width modulation (PWM) control mechanism to regulate the output voltage.
