TLV758P TLV75801PDRVT Voltage Regulator IC Avalon Hashboard

TLV758P / TLV75801PDRVT Linear Voltage Regulator | Adjustable 500mA LDO Replacement for Avalon 1166pro Hashboard Repair

The TLV758P (TLV75801PDRVT) is an adjustable 500mA linear voltage regulator in a 6-WSON (2 × 2 mm) exposed-pad package, used on the Avalon Miner 1166pro hashboard for local low-voltage rail regulation. Output range covers 0.55V to 5.5V — wide enough to cover most local housekeeping rails on the board from a single part number.

Headline numbers for hashboard duty: 6V max input, 0.88V max dropout at 500mA, ultra-low 35µA quiescent current (efficient at light load), 50dB–30dB PSRR across 1kHz–1MHz, and full protection envelope (overcurrent, overtemperature, UVLO, enable input). Compact WSON footprint matched to the dense Avalon 1166pro hashboard layout.

When to Replace the TLV75801PDRVT

• Avalon 1166pro local rail dead — LDO output stuck at 0V or input voltage.
• Hashboard reports out-of-spec rail on diagnostic — LDO drifted or degraded.
• Visible damage on the 6-WSON package after a downstream short event.
• LDO running hot at idle — internal degradation, quiescent current climbing.
• Hashboard boots intermittently — LDO entering thermal shutdown or UVLO under load.

FAQ — TLV75801PDRVT LDO

Q: How do I set the output voltage?
A: Resistor divider between OUT, FB, and GND pins. The Avalon 1166pro board has fixed resistor values matched to the design's target output. Don't change the resistors when replacing the IC — keep the same divider to maintain the original rail voltage.

Q: How do I confirm the LDO is the failed part?
A: Power off, lift the LDO, measure the load side resistance to GND. Healthy load reads finite, shorted load reads 0Ω (fix the load first or the new LDO will die immediately). Re-install LDO, power on, scope OUT — should track the FB divider. Stuck at 0V or input rail = LDO dead.

Q: 6-WSON rework profile?
A: 2 × 2 mm WSON with exposed pad — bottom-side preheat 130–150°C, top-side hot air 320°C with flux paste, brief reflow dwell. The exposed pad must connect to the board's thermal copper. Use a fine-tip soldering iron under a stereo microscope for inspection — the package is very small.
