Working Principle of S-1312C19-M5T1U3 LDO

The S-1312C19-M5T1U3 voltage regulator is based on a proprietary feedback topology to achieve excellent load and line regulation. The feedback topology is characterized by an adjustable hysteretic current limit that provides fast current limit foldback with a low output voltage ripple. The voltage regulator’s internal circuitry limits the current to the minimum level needed to maintain the desired output voltage, and if the load current exceeds the limit, the voltage regulator enters a foldback phase, adjusting the limit accordingly and reducing the voltage output ripple. The current limit value can be adjusted to ensure that the voltage regulator is able to supply sufficient current for a wide variety of applications.

The S-1312C19-M5T1U3 voltage regulator also offers protection against overcurrent and overvoltage conditions by integrating overcurrent sensing circuitry and by monitoring the output voltage. If the output voltage reaches an overvoltage threshold, the voltage regulator enters a shutdown state, protecting the end application from potentially damaging power surges. The S-1312C19-M5T1U3 is also capable of operating in an extremely low input voltage environment, as low as 2.5V.
