ON Semiconductor NCP114BMX330TCG Low Dropout Voltage Regulator

The NCP114BMX330TCG from ON Semiconductor is a high-performance, low dropout voltage regulator designed for applications requiring a regulated and stable voltage supply. This component is particularly well-suited for portable and battery-powered devices due to its low power consumption and small footprint.

Key Features

• Output Voltage: This regulator provides a fixed output voltage of 3.3V, which is ideal for powering a wide range of standard digital ICs and microcontrollers.
• High Accuracy: The output voltage accuracy is ±1%, ensuring reliable and consistent performance for sensitive electronic circuits.
• Low Dropout: With a very low dropout voltage of typically 85 mV at 300 mA load, it maintains regulation even when the supply voltage is very close to the output voltage, maximizing battery life.
• High PSRR: The device features a high Power Supply Rejection Ratio (PSRR) of 75 dB at 1 kHz, which reduces the output noise and ripple when there are fluctuations in the input voltage, making it suitable for noise-sensitive applications.
• Current Limiting: It incorporates current limiting and thermal shutdown features to protect against overcurrent and overheating conditions.
• Low Quiescent Current: The NCP114BMX330TCG is optimized for low quiescent current, drawing only 50 µA, which contributes to extended battery life in portable applications.
