TX78XXMXX

    The TX78XXM series is a group of positive voltage output, three-pin regulators, it provide a high current even when the input/output voltage differential is small. Low power consumption and high accuracy is achieved through CMOS and laser trimming technologies.

    The TX78XXM consists of a high-precision voltage reference, an error amplification circuit, and a current limited output driver. Load Transient response has improved in comparison to the existing series. SOT89, SOT23-3 and SOT23-5 packages are available.

    TX78XXM Typical Application:

    Note1: Cin=Cout=10uF. (10uF Electrolytic capacitor is recommended).
    Note2: If the input and output capacitors are ceramic, add a resistor at the input, as follows.

    Note: Re=(1.2~1.8)Ω.

    Note1:Input capacitor  CIN=10uF.
    Note2:Ouput capacitor COUT=10uF/6.8uF(1uF Tantalum capacitor or 6.8uF ceramic capacitor is
    recommended).
    Note3:The CE port is recommended to connect the current limiting resistor Re. The recommended
    resistance is 10K~47K. When the input voltage is larger than or equal to 12V, it is recommended to add a 0.01uF capacitor Ce.
