Download Datasheet for STMicroelectronics L7815T – 15V Positive Voltage Regulator [24 pages 1994 pdf]
L7815T 15V TO-3 Package Positive Voltage Regulator
– OUTPUT CURRENT UP TO 1.5A
– OUTPUT VOLTAGES OF 15V
– THERMAL OVERLOAD PROTECTION
– SHORT CIRCUIT PROTECTION
– OUTPUT TRANSISTOR SOA PROTECTION
The L7815 series of three-terminal positive regulator is available in TO-3 packages and with fixed output voltage making it useful in a wide range of applications.
These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible.
If adequate heat sinking is provided, theycan deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.
