79M09 is a voltage regulator integrated circuit. It is a member of 79xx series of fixed linear voltage regulator ICs. The voltage source in a circuit may have fluctuations and would not give the fixed voltage output. The voltage regulator IC maintains the output voltage at a constant value. The xx in 78xx indicates the fixed output voltage it is designed to provide. 7909 provides a regulated supply of -09 V and 1A current. Its additional features include internal thermal overload protection, short circuit protection and output transistor safe operating area compensation.
The MC79M00 series of fixed output negative voltage regulators are intended as complements to the popular MC78M00 series devices. Available in fixed output voltage options of −5.0 V, −8.0 V, −12 V and −15 V, these regulators employ current limiting, thermal shutdown, and safe−area compensation, making them remarkably rugged under most operating conditions. With adequate heatsinking, they can deliver output currents in excess of 0.5 A.
Features:
- No External Components Required
- Internal Thermal Overload Protection
- Internal Short Circuit Current Limiting
- Output Transistor Safe−Area Compensation
