General Description
The SR78XXMP 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 SR78XXMP 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. SOT-89 packages are
available.
Block Diagram&Application Circuits
Note:
1.Cin=Cout=10uF. (10uF Electrolytic capacitor is recommended).
2.Re= (1.2~1.8)Ω
.
3. If the input and output capacitors are ceramic, add a resistor at the
input.
4.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 C
