L78 Positive voltage regulator ICs Datasheet - production data 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 TO-220 TO-220FP 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 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) March 2014 DocID2143 Rev 32 1/58 This is information on a product in full production. www.st.comContents Positive voltage regulator ICs Contents 1 Diagram . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 2 Pin configuration . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 3 Maximum ratings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 4 Test circuits . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 5 Electrical characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 6 Application information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25 6.1 Design consideration . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25 7 Typical performance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 35 8 Package mechanical data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 37 9 Packaging mechanical data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 52 10 Order codes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 55 11 Revision history . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 57 2/58 DocID2143 Rev 32
