Description
The L78xx series of three-terminal positive regulators is available in TO-220, TO-220FP, TO-3, D2PAK and DPAK packages and several fixed output voltages, 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, they can deliver over 1 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.
Absolute maximum ratings
| Symbol | Parameter | Value | Unit | |
| VI | DC input voltage | for VO= 5 to 18 V | 35 | V |
| for VO= 20, 24 V | 40 | |||
| IO | Output current | Internally limited | ||
| PD | Power dissipation | Internally limited | ||
| TSTG | Storage temperature range | -65 to 150 | °C | |
| TOP | Operating junction temperature range | for L7800 | -55 to 150 | °C |
| for L7800C | 0 to 150 | |||
Note: Absolute maximum ratings are those values beyond which damage to the device may occur. Functional operation under these condition is not implied.
