MC1469

The MC1469 is a positive voltage regulator designed to deliver continuous load current up to 500 mAdc. Output voltage is adjustable from 2.5 Vdc to 37 Vdc. It is specified for use within themililary temperature range (-55 to +125°C) and the MC1469 within the 0 to +70°C temperature range. For systems requiring a positive regulated voltage, it can be used with performance nearly identical to the MC 1563 negative voltage regulator. Systems requiring both a positive and negative regulated voltage can use the MC1469 and MC1563 as complementary regulators with' a common input ground.

The features of MC1469 can be summarized as (1)electronic "shut-down" control; (2)excellent load regulation (low output impedance -20 milli-ohms typ); (3)high power capability: up to 17.5 Watts; (4)excellent temperature stability: ±0.002 %/°C typ; (5)high ripple rejection: 0.002 %/V typ.

The absolute maximum ratings of MC1469 are (1)input voltage Vin: 35Vdc; (2)peak load current IOK: 250 GPackage/600 RPackage mA; (3)current, pin 2 Ipin 2: 10 GPackage/10 RPackage mA; (4)current, pin 9 Ipin 9: 5.0 GPackage/5.0 RPackage mA; (5)power dissipation and thermal characteristics; (6)operating and storage junction temperature TJ, Tstg: -65 to +150°C; (7)derate above TC=25°C 1/JC: 14.4 GPackage/140 RPackage mW/°C; (8)thermal resistance, junction to case JC: 69.4 GPackage/7.15 RPackage °C/W.
