Introduction

The LT3032MPDE-15#PBF is a linear voltage regulator (LVR) for a wide range of power management applications. This integrated circuit (IC) provides designers with an easy to use, low power, efficient and reliable solution for a variety of voltage regulation needs and applications.

Application Field

The LT3032MPDE-15#PBF is a single-output LVR designed to provide a constant output voltage with good line and load regulation. This voltage regulator can be used to power any low-current DC loads, including in telecommunications, automotive and consumer electronics applications. The LT3032MPDE-15#PBF is able to regulate output voltages from 1.2V to 15V and features a load current limit of up to 500mA. Its integrated thermal shutdown and current limit features protect against overloads and short circuits. The IC is designed with advanced BiCMOS technology and has an operating range of -40° to +125°C. All these features help make the LT3032MPDE-15#PBF an ideal solution for many power conversions and applications.

Working Principle

The LT3032MPDE-15#PBF is an integrated circuit that includes an internal reference, an enabled N-Channel MOSFET and associated components to regulate the output voltage by controlling the switch’s ON/OFF duty cycle. It has an input voltage range of 6V to 40V and an output voltage range from 1.2V to 15V. The output voltage of the voltage regulator is determined by the reference voltage. The reference voltage is compared with an internally generated signal proportional to the output voltage. The IC will then sense the difference between the two and adjust the ON/OFF duty cycle of the internal MOSFET accordingly to maintain a constant output voltage. The IC also features internal protection circuits that detect input and output over-voltages, over-currents, short circuits and thermal overloads. It also has a shutdown input that can be used to disable the device.

Conclusion

The LT3032MPDE-15#PBF provides an easy to use, low power and efficient solution for a variety of voltage regulation needs and applications. It is suitable for regulated power supplies for telecommunications, automotive and consumer electronics applications, as well as other applications requiring controlled voltages from a power source. Its internal protection circuits protect against overloads and short circuits, while its wide input and output voltage range make it an ideal choice for many power conversion and application needs.
