Introduction
S-13D1C3636-A6T2U3 is a linear voltage regulator from STMicro electronics, a global semiconductor leader, amongst the members of ST’s A6T2U product family.Application Field
S-13D1C3636-A6T2U3 is distributed as a solution for applications including low and medium power consumption, low noise, high power density, wide input range, high efficiency, high output current and low power consumption. It can be staffed with internal resistors or external components to tailor the output.The components, which are suitable for general purpose applications include the following:• Intelligent industrial, consumer, and medical applications.• Functional block for intelligent, automotive, and aerospace power systems.• Intelligent AC-DC and DC-DC power systems.• Embedded systems and other high-performance applications.Working Principle
S-13D1C3636-A6T2U3 uses the pulse-width modulation (PWM) technique to maintain a precise output voltage even when the load current changes across a wide range. It operates in two modes: mode selection and PWM mode.In Mode selection mode, the user can set the output voltage to either the preset 1.8 V or the preset 2.5 V. In PWM mode, the output voltage is adjusted dynamically based on the input voltage and output current changes. This technique helps lower the output ripple, power loss, and provides better performance.The device has an integrated control loop to maintain the output voltage across a wide load current range. It provides a precise current foldback to adjust the output voltage with changing load current. This ensures stability in terms of line and load regulation.The device also includes a low-power shutdown mode. If the output voltage is below the under-voltage lockout threshold, the regulator can be disabled by setting the input pin (VIN) to a low logic state. This significantly reduces the quiescent current of the device during light load operations.Conclusion
In conclusion, the S-13D1C3636-A6T2U3 is a linear voltage regulator from STMicro electronics.
