Texas Instruments recommends a compact layout with short traces and minimal vias to minimize noise and parasitic inductance. Place the device close to the power supply and use a solid ground plane to reduce noise coupling. Refer to the application note SLVAE03 for more details.
To ensure stability, make sure to follow the recommended capacitor values and types, and place them close to the device. Also, ensure that the input and output capacitors are properly decoupled from each other and from the power supply. Additionally, avoid using capacitors with high equivalent series resistance (ESR) and ensure that the output capacitor has a low impedance at high frequencies.
The TLV3502AIDCNRG4 can handle input voltages up to 15V, but it's recommended to operate within the specified input voltage range of 2.7V to 5.5V for optimal performance and reliability.
The TLV3502AIDCNRG4 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliability. Refer to the datasheet for more information on thermal derating.
Start by checking the input voltage, output voltage, and output current to ensure they are within the specified ranges. Verify that the capacitors are properly connected and meet the recommended specifications. Use an oscilloscope to check for oscillations or noise on the output. If the issue persists, consult the datasheet and application notes or contact Texas Instruments support for further assistance.
