LT1121IST-5#TRPBF Frequently Asked Questions (FAQ)
-
A good PCB layout for the LT1121 involves keeping the input and output traces short and wide, using a solid ground plane, and placing the input and output capacitors close to the device. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
-
To ensure stability in the LT1121 voltage regulator, it is essential to use the recommended output capacitor value and type, and to place it close to the device. Additionally, the input capacitor should be placed close to the device and should have a low ESR value.
-
The maximum input voltage that the LT1121 can handle is 15V. Exceeding this voltage may cause damage to the device.
-
The LT1121 is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It is recommended to derate the device's output current and voltage at high temperatures.
-
The output voltage of the LT1121 can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage, and R1 and R2 are the resistors in the output voltage divider.
