BA3950A

Regulator ICs System power supply for CD playerequipped audio systems BA3950A With 13.3V (external transistor required), 12V, 10V, and 5.6V outputs, the BA3950A power supply IC is best suited for CD player-equipped audio systems. FApplications CD player-equipped audio systems FFeatures 1) 13.3V (external transistor required), 12V, 10V, and 5.6V outputs are built in (one output for each voltage). 2) Output current limit circuit protects the IC against short-circuiting damage. 3) Thermal protection circuit prevents heat damage to the IC. 4) Compact SIP-M12 package allows a large power dissipation.
