General Description
The HM78XX 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 HM78XX 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, SOT89-5,SOT23-3 and
SOT23-5 packages are available.

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.
