Regarding the change of names mentioned in the document, such as Mitsubishi Electric and Mitsubishi XX, to Renesas Technology Corp. The semiconductor operations of Hitachi and Mitsubishi Electric were transferred to Renesas Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.) Accordingly, although Mitsubishi Electric, Mitsubishi Electric Corporation, Mitsubishi Semiconductors, and other Mitsubishi brand names are mentioned in the document, these names have in fact all been changed to Renesas Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and corporate statement, no changes whatsoever have been made to the contents of the document, and these changes do not constitute any alteration to the contents of the document itself. Note : Mitsubishi Electric will continue the business operations of high frequency & optical devices and power devices. Renesas Technology Corp. Customer Support Dept.

MITSUBISHI <Dig./Ana. INTERFACE> M5292P,FP +12V TRACKING REGULATOR WITH RESET CIRCUIT DESCRIPTION se PIN CONFIGURATION (TOP VIEW) M5292 is a semiconductor integrated circuit designed for voltage regulator which is dual tracking type (positive/ coutecton ~¥e 116] Voc negative output voltage) with system reset circuit. OUTPUT (-) [15] EMITTER OUTPUT (+) Since the output voltage is fixed inside, User can omit the EMITTER OUTPUT (-) (14) sotsestor outside resistors, and this IC includes the system reset circuit ne [4] DETECTION for detecting the abnormal status of Power Supply. When ourrut caw ft — Power Supply of system is in abnormal status, this IC sends BALANCE renin the system reset output (Low) to the MPU/CPU, so User can aouustment cesineut make the system operate safely.
