ME6211A18M3G S5UD 1.8V LDO for Goldshell CK5 Hashboard
The ME6211A18M3G (silk-marked S5UD) is a 1.8 V CMOS low-dropout linear regulator used on the Goldshell CK5 hashboard for ASIC housekeeping rail supply. CMOS process delivers precision, low noise and excellent ripple rejection, with a fast turn-on time for clean power sequencing during boot.
Low-dropout architecture keeps the regulator efficient even when the input rail sags close to 1.8 V — critical for stable hashboard operation under load transients. Built-in short-circuit protection protects the downstream load if a fault develops.
Typical Failure Modes Solved
- 1.8 V rail at 0 V — failed LDO, no chip housekeeping activity.
- Unstable hashrate — degraded regulation under load transients.
- Boot fail / stuck-init — sequencing rail not coming up cleanly.
- Production refurbishment — bulk LDO stock for CK5 rework lines.

FAQ — ME6211A18M3G LDO
Q: ME6211 series — other voltages?
A: Yes — A18 suffix = 1.8 V. Other variants exist at 1.2 V, 1.5 V, 2.5 V, 3.0 V, 3.3 V. Match the silk marking on your board to the right SKU.
Q: Substitute with another 1.8V LDO?
A: Pin-compatible LDOs exist, but verify dropout, noise and ripple rejection match. For OEM-spec CK5 repair, stick with ME6211A18M3G.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com.
