Npct750 Datasheet [upd] May 2026

Nuvoton NPCT750 is a hardware-based Trusted Platform Module (TPM) that implements the

Input and Output Capacitors: Place CIN and COUT as close as possible to the respective pins. The ground return path should be short and direct to the IC’s GND pin.
Kelvin Sense for Feedback: In adjustable mode, connect the feedback resistor divider directly to the VOUT pin (or the output capacitor’s positive terminal), not to the load side. This avoids IR drop errors.
Ground Plane: Use a solid ground plane under the NPCT750. For packages with an exposed pad (e.g., DFN-8), solder the pad to the ground plane for optimal heat sinking.
Noise Bypass: The bypass capacitor (if used) should be a high-quality NPO/C0G ceramic or film capacitor placed within 5mm of the BYP pin.
Thermal Vias: For high current (near 750mA) operation, use an array of thermal vias under the IC’s thermal pad to conduct heat away to inner or bottom layer copper.

Noise Performance: With a mere 4.17 µV_RMS output noise (10 Hz to 100 kHz), this chip is a beast. If you are building a high-end audio DAC or a sensitive ADC reference voltage, this is the go-to component. It effectively acts as a "DC battery."
PSRR (Power Supply Rejection Ratio): It offers 72 dB of PSRR at 60 Hz, meaning it crushes line noise from your wall wart or main supply. This is crucial for clean power.
Adjustability: The A version allows for adjustable output via external resistors, offering flexibility that fixed regulators don't.
Wide Input Range: Supports up to 20V input, making it versatile for various rail voltages (up to about 18V output due to dropout).

The NPC750 features a sophisticated power management system, which includes: npct750 datasheet
