L78 Datasheet Positive voltage regulator ICs Features Output current up to 1.5 A Output voltages of 5 6 8 8.5 9 12 15 18 24 V Thermal overload protection TO- 2 2 0 TO-2 2 0 F P Short circuit protection Output transition SOA protection 2 % output voltage tolerance (A version) Guaranteed in extended temperature range (A version) DPAK D PAK Description The L78 series of three-terminal positive regulators is available in TO-220, TO-220FP, DPAK 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 embeds 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.
