Product Summary

The MC7912C is a 1.0 A Negative Voltage Regulator. Available in fixed output voltage options from -5.0 V to -24 V, the MC7912C employs current limiting, thermal shutdown, and safe-area compensation - making them remarkably rugged under most operating conditions. With adequate heatsinking the MC7912C can deliver output currents in excess of 1.0 A.

Parametrics

MC7912C absolute maximum ratings: (1)Input Voltage (-5.0 V ≥ VO ≥ -18 V) VI: -35 Vdc; (2)Input Voltage (24 V): -40 Vdc; (3)Power Dissipation Thermal Resistance, Junction-to-Ambient θJA: 65 ℃/W; Thermal Resistance, Junction-to-Case θJC: 5.0 ℃/W; (4)Storage Junction Temperature Range Tstg: -65 to +150 ℃; (5)Junction Temperature TJ: +150 ℃.

Features

MC7912C features: (1)No External Components Required; (2)Internal Thermal Overload Protection; (3)Internal Short Circuit Current Limiting; (4)Output Transistor Safe-Area Compensation; (5)Available in 2% Voltage Tolerance (See Ordering Information); (6)Pb-Free Package May be Available. The G-Suffix Denotes a Pb-Free Lead Finish.
