Voltage regulator for printers, electronic typewriters, XY plotters. Voltage regulator for MSX personal computers, floppy disk drive, computer terminals, portable VTRs.Features
ICs having 2 outputs for microcomputer power supply (5V) and motor drive power supply 24, 36V) and being capable of delivering 2 regulated outputs from 1 rectifier. Good efficiency due to chopper type and no beat trouble due to fixed oscillation type oscillator common to 2 outputs. Independent overcurrent protectors for 2 outputs (Foldback characteristics). Output 2 (drive power supply) can be turned ON/OFF by external signal. Two outputs can be also turned ON/OFF simultaneously by an external circuit connected (Refer to Sample Application Circuit). High-precision setting of output voltage, elminating the need to use a variable resistor for adjustment. Input/output Gnd lines are united into one, facilatating combination with other nagative power supply. A negative voltage regulator (5V, 12V, etc.) can be connected externally (Refer to Sample Application Circuit). Output voltage/output current are provided in series.

(Note) 1 Output 2 cutoff (pin 1 input ) : OUTPUT 2 cutoff 1V or less, OUTPUT 3V or greater. 2 The peak current value of OUTPUT (5V) is set 120% of the rating. 3 The peak current value of OUTPUT 36V) is set 200% of the rating considering the motor driving mode. 4 The secondary winding provided in the 5V choke coil makes OUTPUT 15V, 0.3A) available. 5 Peak current setting time.Sample Application Circuit 1 : Standard peripheral circuit
Note 1 The N. C pin (pin 18) must not be used as a relay pin for other line, pin. 2 Pins connected inside the IC must be also connected on the printed circuit board.
