The maximum allowable power dissipation for the LM2661MM/NOPB depends on the temperature and the package. For the MM package, the maximum power dissipation is approximately 1.5W at an ambient temperature of 25°C. However, this value can be derated to ensure reliable operation. Refer to the thermal characteristics section of the datasheet for more information.
The LM2661MM/NOPB is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. Be sure to check the electrical characteristics, thermal characteristics, and reliability data in the datasheet to ensure the device will meet your application's requirements.
The dropout voltage of the LM2661MM/NOPB is the minimum input-to-output voltage differential required to maintain regulation. It can be calculated using the formula: Vdo = (Vin - Vout) / Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current. Refer to the electrical characteristics section of the datasheet for typical and maximum dropout voltage values.
The noise reduction capacitor (CNR) is used to reduce the noise and oscillations in the LM2661MM/NOPB output. It is recommended to use a 10nF to 100nF capacitor between the output and ground pins to ensure stable operation and reduce noise.
Yes, the LM2661MM/NOPB can be used as a 3.3V regulator. However, the output voltage is adjustable and requires an external resistive divider to set the output voltage. Refer to the application section of the datasheet for more information on setting the output voltage.
