AVT1544 A - St1s10 end of linear stabilizers

The integrated impulse stabilizer used in the device easily, and even with a large advantage, replaces the majority of monolithic linear stabilizers.
Monolithic impulse stabilizers have been used in power supplies for many years, but only in recent years have semiconductor manufacturers introduced to the market systems convenient to use:
adapted to work in a wide range of supply voltages without the need to modify the inductance of the choke, characterized by high current efficiency, simple application and small dimensions.
