The recommended input capacitor value is 10uF to 22uF, with a voltage rating of at least 6.3V. This capacitor helps to filter out noise and ripple on the input voltage.
The LM285Z-2.5/LFT7 has an operating temperature range of -40°C to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.
To ensure stability, it's recommended to use a minimum output capacitor of 10uF with an ESR (Equivalent Series Resistance) of less than 5 ohms. Additionally, the output capacitor should be placed close to the device to minimize parasitic inductance and resistance.
Yes, the LM285Z-2.5/LFT7 can be used in an LDO configuration. However, the minimum input-to-output voltage differential (dropout voltage) is typically around 1.5V to 2V, depending on the output current. This means that the input voltage should be at least 2.5V + 1.5V = 4V to ensure proper regulation.
The maximum output current of the LM285Z-2.5/LFT7 is 100mA. However, the device's thermal limitations and power dissipation should be considered when operating at high output currents. It's recommended to check the device's thermal derating curves to ensure reliable operation.
