M5293L

The M5293L is a semiconductor intgrated circuit that is designed as a constant-voltage negative power supply,Since this high-voltage type integrated circuits accepts a maximum input voltage of -60V and provides a fixed output voltage of -32V,it serves,for instance,as an ideal fluorescent character display tube drive power supply.As the output voltage is fixed inside the integrated circuits only a capacitor is needed as the external part.Further,the use of a small-size 5-pin SIP assures high packaging desity for power supply circuits.

The absolute maximum ratings of the M5293L can be summarized as:(1):the symbol is VI,the parameter is input voltage,the rating is -60,the unit is V;(2):the symbol is Pd,the parameter is power dissipation,the rating is 450,the unit is mW;(3):the symbol is Topr,the parameter is operating temperature,the rating is -20 to 75,the unit is ;(4):the symbol is Tstg,the parameter is storage temperature,the rating is -55 to +125,the unit is ;(5):the symbol is ILP,the parameter is load current,the rating is -30,the unit is mA;(6):the symbol is VDIF,the parameter is input/output voltage difference,the rating is 30,the unit is V;(7):the symbol is K,the parameter is thermal derating,the rating is 4.5,the unit is mW/.
