NCP114ASN180T1G Voltage Regulator | CADMIZ-Marked SOT23-5 Fixed 1.8V LDO Replacement IC for Antminer L7 Hashboard and PSU Local Rail Repair
The NCP114ASN180T1G (CADMIZ silkscreen marking) is a fixed 1.8V low-dropout (LDO) voltage regulator in compact SOT23-5 surface-mount package — used on Antminer L7 hashboards for local 1.8V rail generation and on various ASIC miner PSU control sections. Drop-in replacement when the original LDO degrades or fails: restores clean 1.8V rail delivery and clears the chain-scan failures, unstable boot, or peripheral reset issues that come from a degraded LDO.
Built for battery-friendly applications with a wide 1.7V to 5.5V input range — covers both low-voltage rails (3.3V down-regulated to 1.8V) and battery-direct designs. Fixed 1.8V positive output at up to 300mA current matches the standard L7 hashboard local rail draw. Compact SOT23-5 footprint matches the OEM pad layout on most modern hashboard and PSU control board designs.
When to Replace the NCP114ASN180T1G
- 1.8V rail dead or out of spec on an Antminer L7 hashboard — LDO failed open, downstream load receives no power.
- Unstable boot on the hashboard — 1.8V rail not regulating cleanly during startup.
- Visible damage on the SOT23-5 package — burn marks, lifted pins, surge damage.
- PSU control rail failure — replacing degraded 1.8V LDOs on the PSU secondary control side.
- Preventive board refurbishment — refresh peripheral LDOs alongside electrolytics during a complete board overhaul.

FAQ — NCP114ASN180T1G LDO
Q: How do I identify the NCP114ASN180T1G on the board?
A: Look for the CADMIZ silkscreen marking on the SOT23-5 package. The position is typically near 1.8V load components like temperature sensors, EEPROMs, or low-voltage logic ICs.
Q: Is the NCP114 family interchangeable with other SOT23-5 LDOs?
A: Several SOT23-5 1.8V LDOs share the same pinout. The NCP114 offers good quiescent current and stability — useful for sensitive RF / analog applications. For drop-in replacement on a board specifying the NCP114, use the matching part.
Q: What rework equipment do I need?
A: SOT23-5 reflow uses hot-air rework or a fine-tip iron with magnification. Standard equipment for any modern hashboard or PSU control board repair bench.
Q: Bulk pricing for repair shops?
A: Yes — email contact@lys-sz.com with your monthly volume. Reel and tape quantities are stocked.
