NCP177AMX120TCG

NCP177AMX120TCG Description

The NCP177AMX120TCG from onsemi is a high-performance, fixed-output linear voltage regulator designed for precision power management in compact electronic systems. Delivering a stable 1.2V output at up to 500mA, this regulator operates with an ultra-low quiescent current of 90 µA, making it ideal for battery-powered and energy-sensitive applications. Its 5.5V maximum input voltage ensures compatibility with a wide range of power sources, while the 75dB PSRR (1kHz) minimizes noise for sensitive analog and digital circuits. Packaged in a 4XDFN surface-mount form factor with Tape & Reel (TR) packaging, it is optimized for automated assembly processes.

NCP177AMX120TCG Features

• Fixed 1.2V Output: Precision-regulated voltage for low-power ICs and processors.
• High Efficiency: Low dropout and 90 µA quiescent current extend battery life.
• Robust Protection: Integrated over-current (OCP) and over-temperature (OTP) safeguards.
• Low Noise: Exceptional 75dB PSRR ensures clean power delivery.
• Compact Design: 4XDFN package (surface-mount) saves board space.
• Control Flexibility: Enable pin for power sequencing and standby modes.
• Compliance: ROHS3 Compliant, REACH Unaffected, and MSL 1 (Unlimited) for reliability.
