Introduction of S-13A1D33-A6T1U3 Application Field and Working Principle

The S-13A1D33-A6T1U3 single-channel linear voltage regulator is designed to control the output voltage of single channel devices in the PMIC (Power Management integrated circuit) module. This dedicated unit is suitable for a wide range of applications including power distribution, logic and digital circuit protection, temperature sensing and conversion, and AC/DC motor control.

Overview

The S-13A1D33-A6T1U3 is a single-channel, ISO-compliant, low-dropout (LDO) linear regulator featuring equalized output voltage accuracy and improved soft start. It also offers competitive power consumption and excellent line/load ripple rejection. It is able to operate in either a linear or switching mode, depending on the specific application. In normal operation, the output voltage of the device is regulated by a variable voltage reference derived from a low-side optocoupler, which is further regulated by a variable-gain regulator control pin.
