G49IC 1.8V LDO
High withstand voltage LDO 1.8V chip
Chip marking: G49
G49IC 1.8V SGM2202-1.8YN5G/TR is a voltage domain regulator chip, SOT23-5 needle tube, suitable for the maintenance of Antminer L3+ and S9 hash board. Quality assurance, please confirm the miner model with the sales manager before buying.
The SGM2202-1.8YN5G/TR is a 1.8V fixed-output high-precision LDO linear regulator chip, widely used in Antminer hash boards. It has a rated output of 300mA and an input voltage of 1.4V~5.5V. It primarily provides a clean and stable 1.8V low-voltage power supply for the onboard communication bus, logic control unit, signal sampling reference circuit, and detection amplification module, ensuring stable and reliable signal acquisition and data transmission. When it malfunctions, symptoms include abnormal chip overheating, fluctuating 1.8V output voltage, a significant increase in power supply ripple, resulting in a slow decrease in hash rate, incomplete ASIC chip enumeration, frequent communication interruptions and disconnections on the hash board, and continuous power supply on/off cycles, directly impacting mining output.
