BA3940A Product details

Description

193 Regulator ICs FInput / output circuits BA3940A 194 Regulator ICs FElectrical characteristics (unless otherwise noted, Ta = 25_C and VCC = 15V) BA3940A 195 Regulator ICs FCircuit operation Vo1, Vo2 and Vo4 rise when ST pin is 1.8V.With voltage applied on ST, the Vo2 output turns OFF when MODE is 1.6V (typical), and Vo3 turns ON when MODE is 3.2V (typical).BA3940A FApplication example 196 Regulator ICs FOperation notes (1) Operating power supply When operating within proper rang.

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.
