Linear voltage regulators provide a cost-effective way of supplying a regulated output voltage for a variety of applications, from consumer audio equipment to industrial power supplies. One such example is the S-1312C13-A4T2U3 4 Amp Low-Dropout Positive Voltage Regulator featuring a low dropout voltage of 500mV, temperature range of -40°C to +85°C, high switching speed, low quiescent current and overcurrent protection. Although its application fields are broad, this article will focus on the use and working principle of the S-1312C13-A4T2U3 in consumer audio equipment.

Amongst its many application fields, the S-1312C13-A4T2U3 Low-Dropout Positive Voltage Regulator can be used in consumer audio equipment due to its low noise operation and low dropout voltage. Linear voltage regulators provide excellent noise reduction compared to switching power supplies, as any ripple on the input voltage is conditioned and passed to the load with minimal noise. Consequently, this makes them well-suited for audio equipment, as any electrical noise introduced onto the audio signal is minimized. Low dropout voltage, therefore, allows the device to operate within the correct voltage threshold required to regulate the voltage steady to ensure no audio distortion is generated - hence why linear voltage regulators are inherently a better choice for audio equipment.

The working principle of the S-1312C13-A4T2U3 is based on a simple voltage divider circuit. The device contains a preset-regulated voltage which will remain constant regardless of variations in the input supply. Depending on the design of the circuit, the regulated output voltage can be set by adjusting the voltage divider ratio, which can be done through the addition of resistors or capacitors – or any other combination of components. The device then works by diverting any excess current away from the output and supplying it to a bypass path or the load itself.

To maintain the voltage of the output, a control loop is implemented using negative feedback, where the input and output voltages are compared, with any differences in voltage being rectified. This maintains the output voltage at its preset value, regardless of changes to the input voltage. The basic components of this looped control system include an amplifier; an input, output, and feedback connection; and an error amplifier. The S-1312C13-A4T2U3 also has a built-in current limiter which will shut down the device if the output current exceeds a certain threshold. This is a useful safety feature which prevents any damage to the device or other components due to excessive current.

The S-1312C13-A4T2U3 4 Amp Low-Dropout Positive Voltage Regulator is an ideal choice for a variety of application fields, especially those which require low noise operation and low dropout voltage, such as consumer audio equipment. This device contains a preset-regulated voltage which is maintained, regardless of changes in the input supply, by a negative feedback loop. Moreover, an additional current limiter is included for added safety. Therefore, the S-1312C13-A4T2U3 can be used to provide a regulated voltage for multiple applications with minimal distortion and maximum safety.
