Introduction

The LM385BZ-2.5G is a voltage reference device typically used in power management integrated circuits (PMICs). It is a 3-terminal adjustable reference with an output range of 2.5V to 100V. It is an ideal choice for applications requiring a precise and stable reference voltage over a wide dynamic range. In addition to its utility as an adjustable voltage reference, the LM385BZ-2.5G also offers excellent accuracy, low power consumption, and wide temperature range.

Application fields

The LM385BZ-2.5G is a versatile reference device that can be used in a variety of applications. It is most commonly used to provide a stable reference voltage for PMICs, such as in hard-drive controllers and other power-management circuits. It also finds application in regulators, audio amplifiers, analog-to-digital converters, and voltage followers. In addition, the LM385BZ-2.5G can be used as a temperature sensor, as the output voltage is affected by the temperature of its environment.

Working Principle

The LM385BZ-2.5G operates by maintaining a small, fixed voltage across its base-emitter junction that is determined by a band gap reference and a temperature-independent resistor. The voltage output of the LM385BZ-2.5G is adjustable via an external reference voltage. When this external reference voltage is applied, the output voltage of the LM385BZ-2.5G is referenced and adjusted to the voltage applied to it.In order to use the LM385BZ-2.5G in a circuit, the reference voltage is applied to one of the pins (pins 1 or 4) and the output voltage is taken from the other pin (pin 2). The magnitude of the output voltage can be set by adjusting a potentiometer, which alters the current flowing through the reference resistor. This, in turn, adjusts the output voltage.

Conclusion

The LM385BZ-2.5G is a versatile device that can be used in a wide range of applications. It offers excellent accuracy, low power consumption, and wide temperature range, making it an ideal choice for applications requiring a stable and precise voltage reference. The LM385BZ-2.5G operates by maintaining a small, fixed voltage across its base-emitter junction and using an external reference voltage to adjust the output voltage. It is a versatile and reliable device that is widely used in regulation and power management integrated circuits.
