The recommended input capacitor value is 1uF to 10uF, with a voltage rating of at least 6.3V. A larger capacitor can be used for improved noise rejection and stability.
The REG711EA-2.5/2K5 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage as temperature increases to ensure reliability and prevent thermal shutdown.
To ensure stability, use a minimum output capacitor of 2.2uF with an ESR of 0.1Ω to 10Ω, and keep the output capacitor close to the regulator. Additionally, avoid using capacitors with high ESL (Equivalent Series Inductance) values.
The maximum dropout voltage is 1.4V, which means the input voltage must be at least 1.4V higher than the output voltage to maintain regulation.
Yes, the REG711EA-2.5/2K5 is suitable for battery-powered devices due to its low quiescent current (IQ) of 2.5mA and low dropout voltage. However, consider using a low-battery detector or undervoltage lockout circuit to prevent battery drain when the input voltage falls below the minimum required level.
