NCP133AMX150TCG

NCP133AMX150TCG Description

The NCP133AMX150TCG from onsemi is a fixed-output linear voltage regulator designed to deliver a stable 1.5V output with a maximum current of 500mA. This surface-mount device operates with an input voltage range up to 5.5V, making it suitable for low-power applications requiring precise voltage regulation. The regulator features a low dropout voltage of 0.25V @ 500mA, ensuring efficient performance even with marginal input voltages. Packaged in a compact 6XDFN format and supplied in Tape & Reel (TR), it is optimized for automated assembly processes.

NCP133AMX150TCG Features

• High PSRR (80dB ~ 70dB @ 1kHz): Excellent noise rejection for sensitive analog/digital circuits.
• Integrated Protection: Includes over-current, over-temperature, and UVLO (Under Voltage Lockout) for robust operation.
• Enable Control: Allows power management via an external signal, reducing standby power consumption.
• Low Dropout (0.25V @ 500mA): Enhances efficiency in battery-powered applications.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards.
• MSL 1 (Unlimited): No moisture sensitivity concerns for long-term storage.

NCP133AMX150TCG Applications

• Portable Electronics: Ideal for smartphones, tablets, and wearables due to its low dropout and compact footprint.
• IoT Devices: Provides stable power for sensors, microcontrollers, and wireless modules.
• Consumer Electronics: Suitable for audio/video systems, set-top boxes, and other low-voltage circuits.
• Industrial Controls: Reliable performance in PLC modules, instrumentation, and embedded systems.

Conclusion of NCP133AMX150TCG

The NCP133AMX150TCG stands out for its high PSRR, low dropout, and robust protection features, making it a superior choice for applications demanding stable voltage regulation in space-constrained designs. While marked as obsolete, its performance characteristics remain competitive for legacy or niche applications. Engineers should evaluate alternative onsemi regulators for new designs but can leverage this IC for proven reliability in existing systems.
