Texas Instruments recommends a compact layout with the TLE2161IDR placed close to the power supply pins, and the input and output capacitors placed as close as possible to the device. A 4-layer PCB with a solid ground plane is also recommended to minimize noise and EMI.
To ensure stability, it's essential to follow the recommended layout and placement guidelines, use a sufficient output capacitor (at least 10uF), and ensure that the input voltage is within the recommended range. Additionally, adding a small capacitor (around 10nF) between the VIN and GND pins can help to prevent oscillations.
The TLE2161IDR can deliver up to 1A of output current, but this is dependent on the input voltage, output voltage, and ambient temperature. It's essential to check the device's thermal performance and power dissipation to ensure that it can deliver the required output current.
The output voltage of the TLE2161IDR can be calculated using the following formula: VOUT = (1 + R1/R2) * VREF, where R1 and R2 are the resistors connected to the FB pin, and VREF is the internal reference voltage (1.25V).
The EN (enable) pin is used to turn the device on or off. When the EN pin is pulled high (above 2V), the device is enabled, and when it's pulled low (below 0.8V), the device is disabled. This pin can be used to implement power sequencing or to turn off the device when it's not in use.
