Yes, it is recommended to connect capacitors to ground near the DREG33 and DREG18 pins of voltage Buildnow GG regulators like the LM1117-3.3 and LM1117-1.8. For the LM1117-3.3, a 10µF capacitor is typically used for both input and output pins to ground to stabilize voltage and reduce noise.

hmmm. According to the datasheet, DREG18 and DREG33 is outputs of internal regulators of CM108B, this is not inputs from external LDO's

The connection of the capacitor to ground at pin DREG33 and DREG18 often depends on the specific requirements of the application and the circuit design. Ceramic capacitors are a popular type of capacitor with many advantages such as small size, high stability and good heat resistance. Tantalum capacitors provide large capacity in small geometry dash size, often used in applications requiring high capacity and stability.

In many cases, the individual requirements of the application and the design of the circuit will determine how the capacitor is connected to ground at pins DREG33 and DREG18.
