Feature: 1. Linear Regulators: Linear regulators use transistors or FET 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 small current (within 1.5A) high accuracy power supply occasion. 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 Stabilizer Chip: Adopts the voltage stabilizer chip in TO220 package, good heat dissipation and load bearing characteristics, and the module is equipped with high quality heat sink. 5. Stable Work: Control operating temperature <80℃, power dissipation <3W, the module can work stably for a long time (Assistive fan, passive cooling if necessary) Specification: Item Type: Voltage Stabilized Module Material: PCB Quiescent Current: <8mA Load Ripple: <50mV Temperature Drift Coefficient: -1.1mV/℃ Output Noise: 40uV/Vo Voltage Rejection Ratio: >62dB Operating temperature <80℃, power dissipation <3W. Package List: 1 x Voltage Stabilized Module 1 x Wiring Note: The input has no polarity and the output is fixed voltage. The middle wiring is the ground wire, and this port is connected to the middle tap of the transformer during AC input
