The LM4128AMF-3.3/NOPB is a 3.3V Voltage Reference designed for precision power management applications. This device is an ideal choice for the voltage regulation of processors requiring low noise and high accuracy. It is designed to be used in battery and line power applications. The device is available in a wide range of packages, from single to quad-width, to ensure maximum RF shielding and efficient cooling.

The LM4128AMF-3.3/NOPB provides a precise 3.3V output up to a maximum of 7A with a ±2% typical initial accuracy. The device utilizes an Internal Voltage Monitor (IVM) to regulate the output voltage and current. This IVM technology allows the device to accurately regulate the output while minimizing the self-loading of the input power source. The device also includes digital temperature and current monitoring, a fast transient response time, as well as an SMBus/I2C compatible interface.

The LM4128AMF-3.3/NOPB has a wide operating range, making it useful in various types of applications. The device can operate from a single supply of 3.3V to 36V and is excellent for use in portable electronics and automotive applications. The device also features an adjustable under-voltage lockout, over-voltage protection, and over-current protection. This makes it well suited to low-voltage and high-current applications.

The LM4128AMF-3.3/NOPB is designed with a low quiescent current of only 12mA, improving overall efficiency and significantly reducing power consumption. The device uses a simple two-wire serial interface for easy integration into end systems. Additionally, the device includes a power-good output signal, allowing the user to monitor the regulated output accuracy. This signal is useful in redundant systems, where multiple devices can be used in tandem.

The LM4128AMF-3.3/NOPB is an excellent choice for a range of power management applications. Its low noise, fast transient response, wide operating range, and digital monitoring features all make it well-suited for powering processors, FPGAs and other digital logic in harsh environments. Furthermore, its small size and wide availability of packages make it a great choice for applications where space is at a premium.
