General Description
The LD7301 is a low cost linear
regulator producing topquality power supply for high input voltage.
Its features include a 3-terminal fixed output voltage version in TO-92 and SOT-89 packages.
Other than the functions like ordinary low voltage
regulators, the LD7301 provides the use of much higher input voltages (up t...
