Linear voltage regulators are key components in various applications requiring stable DC power. As part of the power management integrated circuit (PMIC) family, the S-13R1A23-A4T2U3 linear regulator offers efficient power management with a variety of features. In this article, we will discuss the application field and working principle of the S-13R1A23-A4T2U3 linear regulator.

The S-13R1A23-A4T2U3 linear regulator provides a 3.3V output with 500mA output current, with input voltages from 2.9V to 6.0V. It is suitable for portable electronic applications requiring a cost-effective DC power solution. It is especially useful in a variety of handheld device applications including mobile phones, gaming systems, and portable media players.

The S-13R1A23-A4T2U3 is based on a linear regulator topology which implements a regulation technique that is dependent on a series pass element, such as a transistor. This series pass element supplies a constant voltage to the output in order to regulate the output voltage. The drive voltage to the series pass element is unequal to the output voltage, which allows the series pass element to dissipate power and generate heat, creating a regulated output voltage.

The S-13R1A23-A4T2U3 offers various protection features, including current limit, thermal shut-down, and overvoltage protection. It is also equipped with an enable pin to make the device operate in low-power mode. The regulator also has a logic controlled enable pin that allows the user to shut down the device with a logic signal. The enable input pins provide increased flexibility to control the regulator through external logic signals, allowing the output voltage to be enabled or disabled depending on the application.

The S-13R1A23-A4T2U3 linear regulator features high efficiency and low drop-out voltage with less than 500mV at full load current. The maximum noise of the device is also low, making it suitable for audio and video applications. Additionally, the S-13R1A23-A4T2U3 features a small form factor and is available in an 8-pin TSSOP package.

In summary, the S-13R1A23-A4T2U3 linear voltage regulator provides a 3.3V output with 500mA output current, with input voltages from 2.9V to 6.0V. It is suitable for a variety of portable electronic applications and offers high efficiency and low drop-out voltage. Additionally, the device offers various protection features and a low noise level. It is available in an 8-pin TSSOP package and is suitable for handheld device applications such as mobile phones, gaming systems, and portable media players.
