Introduction

The LP3907TL-JSXS/NOPB is a Voltage Regulator of the Linear + Switching family of PMIC (Power Management Integrated Circuit) products. It is an integrated linear voltage regulator designed to generate a regulated output voltage of 1.2V with the ability to output a 3.3V or 5V reference voltage depending on the input voltage. It is a single-supply regulator with high efficiency, low quiescent current, adjustable output voltage, and low output noise.

Application Field

The LP3907TL-JSXS/NOPB is a cost-effective and reliable voltage regulator for low voltage applications, such as power supplies for handheld two-way radios, laptops, tablets, GPS receivers and cell phones. Its low input operating range makes it ideal for portable device applications. It can also be used in automotive applications such as lighting, factory automation, enterprise networks, and HVAC systems.

Working Principle

The LP3907TL-JSXS/NOPB is a voltage controlled oscillator (VCO) with an adjustable voltage reference output. It features a feedback topology that utilizes the output current to regulate the output voltage. The VCO frequency depends on the operating voltage and is adjustable with an external resistor. An output voltage is generated by comparing the VCO frequency with a reference oscillator frequency and modulating the output current accordingly. When the output current is adjusted, so is the output voltage, keeping it fixed and stable against supply voltage variation and other components.To increase accuracy, the LP3907TL-JSXS/NOPB has an on-board temperature-sensing circuit that provides negative temperature coefficient (NTC) output voltage compensation. This compensates for any voltage variation due to temperature changes and ensures the output voltage remains stable. This is achieved by setting the output voltage to compensate for temperature and input voltage variation at low supplies and temperatures.

Conclusion

The LP3907TL-JSXS/NOPB is an integrated linear voltage regulator with high efficiency, low quiescent current and low output noise. It is a cost-effective and reliable voltage regulator for low voltage applications, such as power supplies for handheld two-way radios, laptops, tablets and cell phones. It features a feedback topology to regulate the output voltage. With an onboard temperature-sensing circuit, it compensates for any voltage variation due to temperature changes.
