L9474N

L9474N is a special purpose voltage regulator IC (integrated circuit) designed to provide a stabilized voltage and current source in order to power a variety of applications. This voltage regulator can be used for automotive, consumer, medical, industrial and transportation applications. By using this device, the user is able to maintain a stable voltage across a wide range of conditions. The L9474N is a low-dropout (LDO) voltage regulator IC with two standard pin outs for interconnects.

The L9474N performs on-chip regulation of voltage and current, adjusting the output voltage/current in response to changes in load conditions. This LDO voltage regulator is well-suited for applications requiring high amount of power such as automotive applications, where a robust, high-efficiency voltage regulator is needed. Its high precision makes it suitable for critical applications in the medical, industrial and consumer electronics market.

This LDO voltage regulator has an adjustable output in steps of just 75 mV, making it the perfect choice for precision voltage output applications. The L9474N consists of a voltage divider, a main control logic, a regulated output, an error amplifier and a temperature compensation module. In comparison to other LDOs, it offers better thermal noise immunity and high efficiency, giving it advantages over traditional linear voltage regulators.

The working principle of the L9474N device involves two stages. The first stage is the voltage sensing stage where the voltage across the two pins of the voltage divider is sampled. The voltage-sensing signal is then compared with the reference voltage in order to adjust the output current. The second stage is the current-sensing stage, where the current at the output is measured and compared with the reference voltage. This comparison results in a feedback signal, which is then used to adjust the resistance that determines the output voltage.

The L9474N can support up to 1.2 Amps of continuous current and a peak voltage of 8V. It has an excellent temperature range of -40°C to 85°C and a very wide operating frequency range. Its very low quiescent current of just 5 µA makes it perfect for battery-powered applications. The LDO voltage regulator also offers excellent line and load regulation characteristics, making it ideal for high power applications.

The L9474N is a great choice for applications where a stable, high efficiency power source is needed. With its advanced features and good working performance, the LDO voltage regulator provides the required stability and reliability. This device is also cost-effective, making it the ideal choice for budget-focused projects.
