The S-13A1C13-A6T1U3 is a linear voltage regulator designed for a host of electronic applications requiring reliable regulator circuitry. This specific voltage regulator is a single-output, 3-terminal device that is rated up to 1.5 Amps. It is capable of converting an input voltage ranging from 4 to 40 Volts down to a regulated output voltage typically at around 13 Volts DC.

Though one of the more versatile voltage regulators available, there are still several supporting components and considerations which must be made when utilizing this specific regulator device. In most applications, the S-13A1C13-A6T1U3 voltage regulator requires an external series pass transistor, adequate input bypass capacitors, along with at least one output series regulator capacitor. The proper bypass capacitor value is dependent primarily upon the input-level ripple and peak switch current.

It is important to select the appropriate input and output capacitors with the demanded level of ripple current and peak switch current. A sizeable input capacitor is required to be connected in parallel with the input terminal to provide a low-frequency filtering that is able to reduce input ripple current. The output capacitor is also used for noise reduction and to help stabilize the output voltage.

When operating, the S-13A1C13-A6T1U3 voltage regulator follows a basic three-step process. First, the IC charges a large input capacitor, followed by the sensing of the output voltage. Depending upon the detected difference between the current output voltage and the desired voltage value, the IC then adjusts the amount of current it allows to pass through the external pass transistor.

The output voltage is determined by a combination of both the pass transistor and the zener diode. When the sensed voltage and the desired voltage are two different values, the IC adjusts the current level through the pass transistor until the output voltage is the same as the desired voltage, where it will remain until the sensed voltage drifts outside the value of the external voltage reference. The end result is a steady and reliable output voltage.

The combination of low cost, versatility and ease of use makes the S-13A1C13-A6T1U3 voltage regulator an ideal choice for a wide range of applications. This voltage regulator fits a variety of electronics, from consumer products to industrial applications. Examples include consumer audio, automotive battery management, and factory automation.
