The recommended input capacitor value for LP2902M is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce input voltage ripple and improve output voltage regulation.
To ensure stability of the LP2902M regulator, it is recommended to use a minimum output capacitor value of 2.2uF with an ESR (Equivalent Series Resistance) of less than 5 ohms. Additionally, the input capacitor should be placed close to the input pin and the output capacitor should be placed close to the output pin.
The maximum dropout voltage for LP2902M is 1.5V, which means that the input voltage should be at least 1.5V higher than the output voltage to ensure proper regulation.
Yes, LP2902M can operate in a high-temperature environment, but its performance may degrade at temperatures above 125°C. It is recommended to derate the output current and input voltage according to the temperature derating curve provided in the datasheet.
The power dissipation of LP2902M can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current. The maximum power dissipation rating for LP2902M is 1.4W.
