REF191ESZ Frequently Asked Questions (FAQ)
-
The recommended output capacitor value is 10uF to 22uF, but it can be adjusted based on the specific application and noise requirements.
-
To ensure stability and accuracy, it's essential to follow proper PCB layout guidelines, use a low-ESR output capacitor, and maintain a stable input voltage within the recommended range.
-
The maximum input voltage that can be applied to the REF191ESZ is 12V, but it's recommended to operate within the recommended input voltage range of 4.5V to 10V for optimal performance.
-
The REF191ESZ is rated for operation up to 125°C, but it's essential to consider the device's thermal characteristics and ensure proper heat dissipation to maintain accuracy and reliability.
-
To minimize noise and ripple, use a low-ESR output capacitor, ensure a stable input voltage, and consider adding a noise-reducing capacitor (e.g., 10nF) between the output and ground.
