NCP5217AMNTXG

NCP5217AMNTXG is ON Semiconductor’s NCP5217 buck (step-down) regulator IC. It is a compact DC-DC converter in which the high-side switch and control circuitry enable efficient conversion of a higher input voltage to a lower, regulated output for digital rails and other power applications.
Key points:
- Integrated switch-mode regulator with external feedback for adjustable output
- Typical protections: enable/shutdown, overcurrent, overtemperature, undervoltage
- Designed for high efficiency across load ranges and suitable for compact, surface-mount designs
- Used in automotive and consumer electronics, embedded systems, and power rails for CPUs/memory
Note: exact electrical specs (input range, output voltage options, current limit, switching frequency) and package details vary by variant. Please consult the official ON Semiconductor datasheet for NCP5217AMNTXG to confirm specifications and recommended applications.

Pin count: 5 pins (SOT-23-5/SC-70-5).
Function: Adjustable low-dropout regulator (LDO) with enable and feedback. Pins: VIN (input), VOUT (regulated output), GND (ground), EN (enable), FB (feedback for setting the output).

- Manufacturer: ON Semiconductor (ON Semiconductor Corporation).
- What kind of company: A global American semiconductor company that designs and manufactures energy-efficient components (power management ICs, analog, sensors, logic, etc.). Publicly traded on the NYSE (ticker ON), headquarters in Phoenix, Arizona.

NCP5217AMNTXG is a DC-DC buck regulator. Common application areas include:
- Mobile and consumer electronics (smartphones, tablets, wearables) for internal rails
- Automotive electronics (infotainment, body electronics, sensors) requiring wide input range and efficiency
- Industrial and telecom equipment needing efficient point-of-load regulation
- IoT and battery-powered devices (sensors, gateways) for long battery life
- Any system needing compact, high-efficiency DC-DC conversion with low quiescent current.

Package type: MSOP-8 (8-pin micro Small Outline Package). The -XG suffix indicates Tape & Reel shipment and RoHS compliance.
