DD4012SA - 5V High Efficiency Regulator

LM7805/7805 Direct Replacement in TO-220 Pinout

DC-DC voltage converter module provides a high-efficiency 5V output with a 6.5V to 40V DC input voltage (input voltage needs to be approximately 1.5V higher than output voltage).

Quiescent current of approximately 1.5mA with a switching frequency of 550kHz offering efficiency of 76-90%. Features protection against over-temperature, input under-voltage and short circuits.

Pinout is to a standard 2.54mm (0.1") pin pitch, making it a breadboard friendly solution in a small 18.3mm x 10.22m x 6.7mm package.

Can be used as a direct replacement for 5V regulators like the LM7805, L7805 monolithic regulator in a TO-220 case style.

Improving Performance and Reducing Noise (Ripple)

For best performance, it’s recommended to add a capacitor on both the input and output sides. Use a 100 µF electrolytic capacitor on the input (at least 10 µF minimum), and a 10 µF electrolytic capacitor on the output.

Place these capacitors as close as possible to the module’s Vin (input) and Vout (output) pins. This helps keep the input voltage steady and reduces unwanted noise (ripple) in the output, resulting in cleaner and more stable operation.
