Function: 1. Linear Regulators: Linear regulators use transistors or FETs operating in the linear region to subtract excess voltage from the applied input voltage to produce a regulated output voltage. 2. Outstanding Advantages: The advantages of linear regulators are low noise and extremely low quiescent current, suitable for occasions with small current (within 1.5A) and high accuracy. 3. DC Output: Comes with a rectifier and filter circuit, the user only needs to input (AC DC) power and can directly use the stable DC output. The input power connection is not divided into positive and negative. 4. Voltage Stabilization Chip: Uses voltage stabilization chip in TO220 package, good heat dissipation and load-bearing characteristics, and the module is equipped with a high-quality heatsink. 5. Stable Working: Control operating temperature <80℃, power consumption <3W, the module can work stably for a long time (Assisted fan, passive cooling if needed) Specification: Item Type: Voltage Stabilized Module Material: PCB Quiescent Current: <8mA Load Ripple: <50mV Temperature Drift Coefficient: -1.1mV/ Output Noise: 40uV/ Operating Temperature <80℃, Power Consumption <3W. Package List: 1 x Voltage Stabilized Module 1 x Wiring Harness Note: The input has no polarity and the output is fixed voltage. The middle wire is the ground wire, and this port is connected to the transformer's center tap when AC input.
