BA3940A - System power supply for CD radio cassette players

Description

FCircuit operation Vo1, Vo2 and Vo4 rise when ST pin is 1.8V.

Features

  • 1) One 9V output, two 7V outputs (switched by MODE SW, only one output is available at the same time) and one 5V output are built in. 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. FAbsolute maximum ratings (Ta = 25_C) FRecommended operating conditions (Ta = 25_C) 192 Regulator ICs FBlock diagram BA3940A FPin.
