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 (t5V, 3V) are fixed inside, and Veo!) [i] + Vco(!) this IC includes pull-up registor (10k) of reset output, BALANCE [3] [is] REFERENCE User can omit the outside parts. #5V output is low power aN sway dissipation type, that is to say, this is able to operate even wo iv ® if input-output voltage difference is very low status such as ono [4] 13) + vee 0.2V (@lo = +100mA). Therefore, User can shrink the input —Veo(2) +Vo (2) transformer awd Gl ON/OFF User can be prevent making a noise by means of operating Vina [ig ca mute function before Power supply (45V) of Amplifier starts cos [BI fe] ast up, for 3.0V regulator for mute function starts up earlier than +8V output Outline 16P4
