General Description
The LD7301 is a low cost linear regulator producing top-
quality 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 to 450V).
It eliminates the need for large power resistors when used
in a SMPS startup circuit. In this application, current is
drawn from the high voltage line only during start-up.
There is only current flow leakage after start-up, thereby
reducing the continuous power dissipation from milliwatts
to watts.
