Introduction

The LM385BYZ-1.2/NOPB is a precision adjustable voltage reference in the PMIC (Power Management Integrated Circuit) product family. It is a three-terminal adjustable voltage reference that is optimized for accuracy and low temperature drift. It is designed for a wide range of industrial and consumer applications that require the reference to operate over a wide range of temperatures.

Application Field

The LM385BYZ-1.2/NOPB has a wide range of applications in the industrial and consumer markets. It can be used in process control and data acquisition systems, power supplies, motor controllers, robotics, medical instruments, and consumer electronics. In addition, the device can be used in circuits where precision voltage references are required.

Working Principle

The LM385BYZ-1.2/NOPB is a three-terminal adjustable voltage reference. When power is applied to the device, an internal band-gap reference circuit generates an output voltage that can be adjusted from 0.8 V to 2.6 V, with a typical accuracy of 0.25%.

The device uses an N-type MOSFET device to vary the output voltage without affecting the temperature coefficient of the reference. This provides for a stable output voltage over the full operating temperature range. The device also has very low junction-to-junction offset to ensure that the output voltage is accurate over an extended temperature range.

The LM385BYZ-1.2/NOPB has a typical temperature coefficient of 10 ppm/°C and a maximum of 15 ppm/°C over the specified temperature range. The output voltage is adjustable with a ±5%, ±10% or ±20% error, depending on the design.

The LM385BYZ-1.2/NOPB is capable of driving up to 10 mA of load current. The device is available in 8-pin PDIP, 8-pin SOIC and 8-pin MSOP packages. It is pin-compatible with other voltage references in the PMIC product family.
