WL2836E08-5/TR 0.8-3.3V LDO Regulator for Antminer S19j / S19j Pro
The WL2836E08-5/TR is a low-dropout CMOS linear regulator used on Antminer S19j and S19j Pro hashboards for ASIC housekeeping rail supply. Precision regulation + fast transient response deliver clean low-noise power to the chip housekeeping domain — critical for stable hashrate under load transients.
Wide flexibility: 1.4 V – 5.5 V input range and 0.8 V – 3.3 V output range cover the standard ASIC core / housekeeping rail set. Headline specs: 300 mA output with 50 µA quiescent current, plus thermal overload + short-circuit protection for safe operation under fault conditions.
Typical Failure Modes Solved
- Housekeeping rail at 0 V — failed LDO, no chip enumeration.
- Hashboard fails to boot — ASIC core rail sequencing broken.
- Unstable hashrate — degraded regulation under transient load.
- Production refurbishment — bulk LDO stock for S19j rebuild lines.

FAQ — WL2836E08-5/TR LDO
Q: Adjustable output — how is the voltage set?
A: External resistor divider on the FB pin programs the output voltage anywhere from 0.8 V to 3.3 V. Match the original divider when replacing — wrong divider = wrong rail voltage.
Q: Drop-in replacement for failed S19j LDO?
A: Verify silk marking + footprint match. For OEM-spec S19j / S19j Pro repair, stick with WL2836E08-5/TR rather than substituting an arbitrary 300 mA LDO.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com.
