Power Supply Regulator

Product Specifications

Technical details and manufacturing context for Power Supply Regulator

Definition

A power supply regulator is a critical electronic component within Central Processing Units (CPUs) and controllers that ensures consistent, stable voltage delivery to sensitive semiconductor circuits. It monitors input voltage fluctuations and adjusts output to maintain precise voltage levels required for reliable processor operation, preventing damage from voltage spikes or drops. This directory entry covers a generic component type used in computer, electronic and optical product manufacturing. The regulator typically operates over an input voltage range of 9–36 V DC, providing a fixed output of 5 V DC ±2% for logic circuits, with a continuous output current of 0.5–3 A. Key performance parameters include line regulation of ±0.2%, load regulation of ±0.5%, ripple and noise of ≤50 mV peak-to-peak at full load, and efficiency of 85–95% at nominal input and full load. The component is designed for an operating temperature range of -40 to 85 °C and a storage temperature range of -55 to 125 °C. It offers an ingress protection rating of IP54–IP65 per IEC 60529, and an isolation voltage of 1500 V DC between input and output. The standard DIP package dimensions are 25.4×15.2×10.2 mm, with a weight of 15–30 g depending on power rating. Materials typically include silicon semiconductor, copper conductors, ceramic substrate, and epoxy encapsulation. These values are directory reference ranges and must be confirmed for the specific model and application with the legal manufacturer or supplier. The regulator is a component, not a standalone product, and its suitability depends on the target circuit's requirements. Always verify model-specific specifications and standards compliance with the manufacturer before integration.

Working Principle

The regulator compares the output voltage to a reference voltage using feedback circuitry. When deviations are detected, it adjusts the conduction of transistors or uses switching elements to maintain the desired output voltage. Linear regulators dissipate excess voltage as heat, while switching regulators convert and regulate voltage more efficiently through pulse-width modulation. The feedback loop continuously monitors the output and corrects for input voltage changes and load variations, ensuring stable operation of the connected CPU or controller circuits.
