LM385BLPRE3-1-2 is a precision voltage reference, which is typically used in applications involving low power consumption. This voltage reference is also referred to as a PMIC (power management IC) and is used to precisely control the voltage in a circuit. It is a low-power voltage-stabilizing device and is one of the most popular voltage references used in modern commercial products.
The LM385BLPRE3-1-2 provides a very precise voltage reference with a stability of 1mila-volts (mV) over a temperature range of -55°C to +125°C. It can be used to provide a stable and accurate reference voltage for a wide range of applications, including consumer electronics, communications, and medical instrumentation. It is also commonly used in industrial control and machine control systems, automotive electronics, and military applications.
The LM385BLPRE3-1-2 is based on a simple, but effective, voltage reference circuit. The reference voltage is derived by combining two voltage sources, a voltage reference and a voltage regulator, in a feedback control system. The reference voltage is produced by the voltage reference, which is typically a Zener diode or some other type of voltage reference device. The voltage regulator is usually a linear regulator, such as an LM317, which is used to adjust the output of the reference voltage to achieve the desired reference voltage. The feedback system compares the output voltage of the voltage regulator to the reference voltage and adjusts the output of the voltage regulator accordingly.
The LM385BLPRE3-1-2 is powered by a single 3V supply and is easy to program, with single-button control for setting the output voltage. The output voltage is adjustable from 0 volts to the full supply voltage and can be configured in four different reference levels and two different input models. The device is available in two different termination options (wire and solder) and can accept both standard and low voltage inputs. The package size is small, making it ideal for space-constrained applications.
In conclusion, the LM385BLPRE3-1-2 is an excellent choice for applications requiring a low-power and accurate voltage reference. It is a popular and reliable voltage reference and has been used in many applications over the years. The device has an impressive temperature stability of 1mV over a relatively wide range. It is easy to configure and program and is available in different packages and input models. With its small package size, integration into existing circuits is straightforward.
