The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and desired noise rejection. A larger capacitor value can provide better noise rejection, but may also increase the startup time.
No, the LM385BXMX-1.2/NOPB is a low-dropout voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, but it is not designed to handle high currents. For high-current applications, a dedicated voltage regulator such as the LM1117 or LM317 should be used.
To ensure stability and accuracy over temperature, it is recommended to use a bypass capacitor on the output pin, and to keep the input voltage within the recommended range. Additionally, the device should be operated within the recommended temperature range, and the PCB layout should be designed to minimize thermal gradients and noise.
Yes, the LM385BXMX-1.2/NOPB is suitable for use as a voltage reference for ADCs or DACs. Its low noise and high accuracy make it a good choice for precision analog-to-digital or digital-to-analog conversion applications.
The typical startup time for the LM385BXMX-1.2/NOPB is around 10ms to 20ms, depending on the input voltage and capacitor values. This is the time it takes for the device to reach its stable output voltage after power-on.
