Infineon Technologies OPTIREG™ TLE4471GNUMA1 is a triple linear voltage regulator designed for automotive applications. This device offers three independently regulated positive outputs with adjustable voltage capabilities, providing 5V fixed output and tracking outputs. The primary output can deliver up to 450mA, with secondary outputs capable of 50mA and 100mA respectively. Key control features include enable, reset, and watchdog functionalities. Protection mechanisms are robust, encompassing over-temperature, over-voltage, reverse polarity, short-circuit, and transient voltage suppression. The regulator exhibits a quiescent current of 1.8mA and a low dropout voltage, with specific values of 0.55V at 450mA, 0.6V at 50mA, and 0.6V at 100mA. Power supply rejection ratio (PSRR) is rated at 30dB across the 20Hz to 20kHz frequency range for all outputs. Packaged in a PG-DSO-20 (20-SOIC) and supplied on tape and reel, this AEC-Q100 qualified component is suitable for demanding automotive environments operating between -40°C and 150°C junction temperature.
