MITSUBISHI <Dig./Ana. INTERFACE> 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 PIN CONFIGURATION (TOP VIEW) 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 ~Veo41) +Voo(1) this IC includes pull-up registor (10k2) of reset output, BALANCE REFERENCE User can omit the outside parts. +5V output is low power ADIUSTVENT in vor dissipation type, that is to say, this is able to operate even ° av ) if input-output voltage difference is very low status such as ono [4] co 0.2V (@lo = +100mA). Therefore, User can shrink the input —Voo(2) +Vo (2) transformer. compenstiAS5 | [ii] on/ore User can be prevent making a noise by means of operating Vu {ig} co mute function before Power supply (#5V) of Amplifier starts coa [BI [a] asT up, for 3.0V regulator for mute function starts up earlier than +5V output.
