BA78□□Series,BA78M□□Series
No.12019ECT01
●Description
BA78□□, BA78M□□ series are three-terminal regulators available with several fixed output voltages. It supplies the
stable fixes voltage from unstable direct input voltage. The useful output voltage lineup is 5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V,
18V, 20V, 24V with 0.5A / 1A current ability. They have nearly same electric characteristics as competitor products and cover
a wide range of application.
●Features
1) Built-in over-current protection circuit and thermal shutdown circuit
2) High ripple rejection
3) Available TO220CP-3, TO252-3 package to a wide range application
4) Compatible replacement to competitor products
5) Various voltage lineup (5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V, 18V, 20V, 24V)
●Applications
Fixed voltage power supply for TV, Audio components, etc
