L79 Negative voltage regulators Datasheet - production data Description TAB The L79 series of three-terminal negative regulators is available in TO-220, TO-220FP and 3 1 DPAK packages and several fixed output 2 D PAK 3 voltages, making it useful in a wide range of 2 1 applications. TO-220FP TAB These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation 3 furthermore, having the same voltage option as 2 1 the L78 positive standard series, they are TO-220 particularly suited for split power supplies. If adequate heat sinking is provided, they can deliver over 1.5 A output current. Features Although designed primarily as fixed voltage Output current up to 1.5 A regulators, these devices can be used with external components to obtain adjustable Output voltages: -5, -8, -12, and -5 V voltages and currents. Thermal overload protection Short-circuit protection Output transition SOA protection Output tolerance 2% (AC version) or 4% (C version) at 25 C Table 1: Device summary Order codes Output voltages TO-220 TO-220 DPAK TO-220FP (single gauge) (dual gauge) L7905ACV L7905ACV-DG L7905ACD2T-TR -5 V L7905CV L7905CV-DG L7905CD2T-TR L7905CP -5 V L7908CV L7908CV-DG -8 V L7912ACV L7912ACV-DG -12 V L7912CV L7912CV-DG L7912CD2T-TR L7912CP -12 V L7915ACV L7915ACV-DG -15 V L7915CV L7915CV-DG L7915CP -15 V September 2017 DocID2149 Rev 23 1/27 www.st.com This is information on a product in full production.
