About the Product

AW37030D120STR 1.2V LDO Chip for Antminer Hash Board Repair

The AW37030D120STR (silk marking: VGML AA) is a 1.2V low-dropout regulator widely used on Antminer hash boards. It is commonly installed on S21 IMM, S21XP, S21, T21, KS5, KS5PRO, K7, KA3, KS3, HS3, S19jpro, S19jpro+, S19XP and other Bitmain models to stabilize core chip power rails.

Reliable Replacement LDO for ASIC Miner Maintenance

This device integrates current limit, short circuit protection and thermal shutdown to prevent damage during heavy miner workloads. Featuring high PSRR, low noise, and low dropout voltage, it ensures stable hashing performance and reduces failure rates of hash board power circuits.
