Part Description: Precision 1 A regulators


Part Details:

L78xxAB L78xxAC Precision 1 A regulators Features Output current in excess of 1 A Output voltages of 5; 6; 8; 9; 12; 15; 24 V Thermal overload protection Output transition SOA protection 2 % Output voltage tolerance Guaranteed in extended temperature range TO-220 TO-220FP Description The L78xxAB L78xxAC series of three terminal positive regulators are available in TO-220,TO-220FP, and D2PAK packages and several D2PAK fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problem 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.
