MP2019GN Linear Regulator for Antminer ASIC and Crypto Mining Maintenance

MP2019GN Linear Regulator | Wide 3-40V Input Range / 300 mA Output Low-Dropout Voltage Regulator with 10 µA Ultra-Low Quiescent Current for Antminer T15 / S17 / T17 / S19 / S19+ / S19 XP / S19j Pro Hashboard

Repair your crypto mining equipment with the MP2019GN linear regulator, a high-performance replacement chip designed specifically for Antminer ASIC hashboards and control boards. With its advanced features and precise voltage control, this regulator ensures optimal power delivery and stability for your mining operations. Restore the housekeeping rail on Antminer T15, S17, T17, S19, S19+, S19 XP, and S19j Pro hashboards with the MP2019GN — enhancing performance and longevity of the affected miners.

The MP2019GN offers a wide input voltage range of 3V to 40V, making it compatible with the broad voltage envelope across multiple Antminer generations. Its low quiescent supply current of only 10 µA minimizes power consumption, while stability with low-value output ceramic capacitors improves efficiency and PCB layout flexibility. With a specified current of 300 mA, the MP2019GN ensures consistent and reliable power output for housekeeping circuitry.

Typical Use in Antminer Hashboard Repair

• Hashboard housekeeping rail failure — MP2019GN typically powers low-current housekeeping circuits on Antminer hashboards.
• Control-board low-power rail — restoring 3.3V / 5V outputs to small downstream loads.
• Post-fault recovery — LDO often takes collateral damage when downstream load shorts.
• Production refurbishment — bulk LDO inventory for high-volume hashboard rebuilds.
• General low-power LDO use — any 3-40V input with low-current output need.

MP2019GN Specifications

FAQ — MP2019GN LDO Regulator

Q: How do I diagnose a failed MP2019GN on hashboard?
A: Typical signs: downstream housekeeping rail (3.3V or low-current 5V) absent on the secondary side, hashboard control / supervisor circuit doesn't boot, no I²C / SPI activity from the board. Test by measuring DC voltage on the LDO output pin with PSU plugged in — should match nameplate spec. Short or open indicates failure.

Q: Can I substitute another LDO with similar input range?
A: Functionally yes — any LDO with similar Vin range (3-40V), Iout (300mA+), low Iq (<100µA) in matching package works. However, the MP2019GN has specific pin assignments and footprint. For OEM-spec repair, stick with MP2019GN. Sub-millimeter pad differences will require PCB rework to substitute.

Q: Why such low quiescent current (10 µA)?
A: Hashboard housekeeping rails operate 24/7. At 10 µA Iq vs typical 100-500 µA for older LDOs, the MP2019GN saves measurable standby power that compounds across thousands of miners in a facility. Lower Iq also reduces thermal load on the LDO itself, improving long-term reliability.

Q: Bulk pricing for Antminer repair shops?
