Fast-response, Wide-range Voltage Regulators Are Typically More Expensive.

wide range stabilizer for ac requires more advanced processes and control architectures; some industrial and automotive-grade products even employ high-performance CMOS-DMOS BCD processes to balance input range and dynamic performance. These technologies demand greater precision in transistor selection, feedback control networks, and stability compensation, thus driving up development and manufacturing costs.

Wide-range regulators handle input voltages ranging from very high to very low. Their internal circuit design must consider cross-voltage performance, voltage regulation loop stability, and transient dynamics. This makes material selection, packaging specifications, and testing and verification in the supply chain more stringent. Suppliers often require more engineering resources to optimize these designs, resulting in these products generally being more expensive than narrow-range regulators.
