Application Field

The LM385BD-1.2 is designed with a wide range of applications in mind. It is particularly suited for critical analog applications, such as data/communications equipments. It is also well-suited for projects that require an adjustable power supply, or when you need a highly accurate reference voltage over time.

The LM385BD-1.2 can be used for the following applications:

• Analog signal conditioning
• Data converter references
• Data and communications equipment
• Power management
• Reference voltage generation
• High-accuracy measuring circuits

Working Principle

The LM385BD-1.2 is designed to provide a very precise and stable output voltage. It has a 0.04% temperature stability and a 10ppm/°C voltage drift. This can be attributed to its sophisticated temperature sensing and adaptive voltage regulation algorithm, which ensures an accurate output voltage during periods of varying temperatures.

The LM385BD-1.2 operates by taking an incoming voltage from a power source and then regulating this voltage to a fixed output voltage. This is achieved by having two transistors – a P-channel and an N-channel – that form the voltage regulating circuit. The P-channel transistor receives a constant current while the N-Channel transistor regulates the constant voltage as per the reference. The regulated voltage is then output to the supply terminals.

The LM385BD-1.2 is also designed to operate in low power conditions, making it suitable for battery-powered applications. It is also designed to minimize noise due to the spread spectrum shift and uses the latest CMOS technology to reduce the power consumption further.

Conclusion

In conclusion, the LM385BD-1.2 is a well-regarded voltage referencing device, that is capable of lasting through long periods of varying temperatures with great accuracy. It is used extensively in communications, power management, and measuring applications. Its sophisticated circuitry makes it well-suited for applications requiring precise and reliable output voltages.
