Furthermore, a quiescent current reduction circuit has been included • Dropout Voltage Typically 0.5V at IO = 1A which reduces the ground pin current when the • Output Current in Excess of 1A differential between the input voltage and the output • Trimmed Reference Voltage voltage exceeds approximately 3V. The quiescent current with 1A of output current and an input-output • Reverse Battery Protection differential of 5V is therefore only 30mA. Higher • Internal Short Circuit Current Limit quiescent currents only exist when the regulator is in • Mirror Image Insertion Protection the dropout mode (VI − VO ≤ 3V). • TTL, CMOS Compatible ON/OFF Switch Originally designed for vehicular applications, the LM2941 and all regulated circuitry are protected from reverse battery installations or two-battery jumps. During line transients, such as load dump when the input voltage can momentarily exceed the specified maximum operating voltage, the regulator will automatically shut down to protect both the internal circuits and the load. Familiar regulator features such as short circuit and thermal overload protection are also provided.
