L78xx, L78xxC, L78xxAB, L78xxAC Positive voltage regulator ICs Datasheet - production data Description The L78xx series of three-terminal positive regulators is available in TO-220, TO-220FP, TO- 3, 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 TO-220 TO-220FP 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 TO-3 DPAK DPAK current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable Features voltage and currents. Output current up to 1.5 A Output voltages of 5 6 8 8.5 9 12 15 18 24 V Thermal overload protection Short circuit protection Output transition SOA protection 2 % output voltage tolerance (A version) Guaranteed in extended temperature range (A version) Table 1.
