Description
L7812 LM7812 12V 3A Voltage Regulator Power Supply Fully Wave Bridge Rectifier Converter Rectifier Filter Regulator
Product Description
This board adopts full-wave bridge rectification, AC and DC can be input, and the input is regardless of positive and negative. The filter adopts two 35V 220UF large-capacity electrolytic capacitors as buffer filters to make the output current stable and smooth. L7812 is equipped with heat sink and 3A rectifier bridge, which can meet the continuous output of large current.

Parameters

Module size: 43mm*20mm Input voltage (withstand voltage): DC: 15~24V, Exchange: 12~18V Output characteristics: Load regulation rate: 100mV Quiescent current: 8mA Output noise voltage: 42uV Input and output pressure difference: 2V Output impedance: 15mΩ Peak current: 1.5A
Feature
1
3A rectifier bridge (AC and DC can be input)
2
2*35V 220UF high withstand voltage capacitor (do buffer filter)
3
