LM385BM-1.2/NOPB

The LM385BM-1.2/NOPB is an adjustable low-dropout (LDO) voltage reference in the form of a noisy regulator that is designed to be used in applications such as precision DACs and A/D converters, as well as any other design where an accurate voltage reference is required. It offers excellent output noise performance as low as 0.1 ppm/°C, even over large temperature ranges. It also provides low output impedance and low drift over temperature and time. The device is supplied in an industry standard 8-lead SOIC package.

The LM385BM-1.2/NOPB is part of a family of precision adjustable voltage references which includes the LMH6465 and the LM385CM-1.2/NOPB. The LM385BM-1.2/NOPB has a dropout voltage of 1.2V, while the LMH6465 has a dropout voltage of 0.7V and the LM385CM-1.2/NOPB has a dropout voltage of 1.7V.

The LM385BM-1.2/NOPB can be used to regulate the output voltage of a voltage regulator, such as an LM337. It is a monolithic IC composed of two precision band-gap references, a noise generator, an error amplifier, and two output control transistors. The output voltage is set by connecting a resistor divider between pin 5 (ADJ) and pin 7 (GND). The voltage on pin 5 sets the output voltage. The output voltage can also be adjusted with an external resistor divider, allowing the user to set a more precise output voltage.

The LM385BM-1.2/NOPB can be used in many applications such as precision DACs, A/D converters, pressure sensors, and other applications which require good noise performance, low drift, and good temperature stability. It is also used to set the voltage of optical communication system, machine vision systems, security systems, and other precision applications which require a low-noise stable voltage reference.

The LM385BM-1.2/NOPB has a temperature coefficient of 0.1 ppm/°C. This makes it suitable for applications which require a high level of accuracy and performance over a wide temperature range. It also has low noise, low output impedance and low drift over temperature and time.

In summary, the LM385BM-1.2/NOPB is a robust, low-noise and highly stable voltage reference device. It offers an adjustable output voltage and excellent performance over a wide temperature range. It is suitable for precision DACs, A/D converters, pressure sensors, optical communication systems, and other applications requiring a low-noise and stable voltage reference.
