INTERFACE> MS294P SYSTEM RESET IC WITH LOW INPUT-OUTPUT VOLTAGE DIFFERENTIAL TYPE+SV REGURATOR, AND 3.0V REGULATOR FOR MUTE FUNCTION DESCRIPTION M5294P is a semiconductor integrated circuit designed for dual tracking type voltage regulator, which includes system reset circuit, and 3.0V regulator for mute function. Since the output voltage (+5V, 3V) are fixed inside, and this IC includes pull-up registor (10k92) of reset output, User can omit the outside parts. +5V output is low power dissipation type, that is to say, this is able to operate even if input-output voltage difference is very low status such as 0.2V (@lg = +100mA). Therefore, User can shrink the input transformer. User can be prevent making a noise by means of operating mute function before Power supply (+5V) of Amplifier starts up, for 3.0V regulator for mute function starts up earlier than +5V output.
