Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to route the input and output signals on separate layers to minimize noise and crosstalk. Additionally, it's recommended to use a 10nF capacitor between the VIN and GND pins to filter out high-frequency noise.
To ensure proper power-on and power-off sequencing, Texas Instruments recommends applying power to the VIN pin first, followed by the EN pin. When powering off, the EN pin should be turned off before removing power from the VIN pin.
The XTR117AIDRBT 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 consult the datasheet and perform thermal calculations to ensure the device operates within its recommended operating conditions.
To optimize the XTR117AIDRBT for low noise and high power supply rejection ratio (PSRR), Texas Instruments recommends using a low-ESR output capacitor, minimizing the PCB trace length and inductance, and using a high-quality input capacitor. Additionally, the device should be operated within its recommended input voltage range.
The EN (enable) pin is used to turn the XTR117AIDRBT on and off. When the EN pin is high, the device is enabled, and when it's low, the device is disabled. The EN pin can be connected to a logic signal or a switch to control the device's power state.
