A good PCB layout for the LM20136MHE/NOPB should include a solid ground plane, wide power traces, and a thermal relief pattern under the device to facilitate heat dissipation. TI provides a recommended PCB layout in the datasheet.
To ensure stability, it's essential to follow the recommended capacitor selection and placement guidelines in the datasheet. Additionally, ensure that the output capacitor has a low ESR and is placed close to the output pin.
The LM20136MHE/NOPB can handle input voltages up to 42V, but it's recommended to operate within the specified input voltage range (3.5V to 36V) for optimal performance and reliability.
The LM20136MHE/NOPB has built-in overcurrent protection (OCP) and thermal shutdown (TSD) features. However, it's still essential to add external protection components, such as fuses or PTC resistors, to prevent damage from excessive current or temperature.
The LM20136MHE/NOPB is rated for operation up to 125°C, but it's essential to consider the device's power dissipation and thermal management when operating in high-temperature environments. Ensure proper heat sinking and thermal design to prevent overheating.
