The LM2930 series of linear regulators are a type of power management integrated circuit (PMIC) designed for maximum efficiency and accuracy. They are typically used in mobile and embedded devices, where high power is required from small form factor packages. The LM2930 series is available in a variety of packages, with a choice of input and output voltage levels. As a PMIC, the LM2930 series can provide a low-noise supply voltage to precision analog and digital circuits, and can also reduce power consumption through “sleep” and “shutdown” modes. The LM2930S-8.0/NOPB is a member of this series. It is a low-dropout (LDO) linear regulator with an input voltage range of 2V to 18V, and an output voltage of 8.0V. Moreover, it is capable of providing constant voltage and current with excellent load and line regulation.

The LM2930S-8.0/NOPB is well-suited for applications such as handheld computing, telecommunications and testing equipment, as it helps reduce system power consumption and provides a clean, low-noise output suitable for powering sensitive circuits. The device is based on the series-pass configuration, which involves a pass FET (Field Effect Transistor), whose gate voltage is determined by the error amplifier. Whenever the output voltage drops, the error amplifier increases the gate voltage of the pass FET, triggering an increase in current flow. This method provides a controlled and efficient regulation of the output voltage, even in the event of large loads.

The LM2930S-8.0/NOPB features 10 µA of maximum operating current and an integrated over temperature protection circuit, which decreases the current when temperature exceeds the design limit. Its low quiescent current is beneficial for battery-powered applications, while its low dropout voltage allows it to operate even when the input voltage is close to the output voltage. This is especially beneficial in battery backup systems, as it extends the operational time in the event of depletion.

In addition, the LM2930 series also includes a programmable Soft-Start feature, which ensures a controlled start-up when the input voltage is supplied. This allows the device to reduce inrush current, which can be beneficial in DC/DC converters, as it helps to reduce power consumption and stress on the components. The open loop and short circuit protection are another defining characteristics of the series, providing additional reliability and protecting the device from damage.

Overall, the LM2930S-8.0/NOPB is an excellent choice for low-voltage, high-efficiency linear regulation in mobile and embedded devices. Its wide voltage ranges, low quiescent current, and integrated protections make it well-suited for a variety of applications. It can help reduce system power consumption and provide reliable, low-noise supply voltages to precision analog and digital circuits, and can even extend battery life in the event of unexpected depletion.
