Working Principle

The LD6836TD/33P,125 is a CMOS circuit that is based on the principle of “charge pump.” Its main schematic of the circuit is shown in the figure below.

The circuit is designed such that the output current is limited to 3A ±2A. The input voltage is applied to the capacitor, which is then charged or discharged by the current flowing through MOSFETs depending on the output voltage. Thus, the output voltage is kept constant by controlling the gate of MOSFETs. The accuracy of the output voltage is maintained better with the adaptive voltage scaling (AVS) feature and the input voltage is protected against overvoltage condition with the overvoltage protection (OVP) feature.

The LD6836TD/33P,125 has very low dropout voltage, which ensures that it can work even at very low input voltages. This makes it ideal for applications such as in portable or battery powered applications or converters working on AC/DC or DC/DC conversions. The LD6836TD/33P,125 also has a current limiting and thermal protection feature which makes it reliable and safe in operation.

To sum up, the LD6836TD/33P,125 is a high performance linear voltage regulator that is suited for low-cost, low-voltage applications where space-saving and improved accuracy are critical considerations. Its advanced features, such as overvoltage protection, current limiting and thermal protection, allow it to function safely and accurately in a wide range of applications, making it an ideal choice for designers.
