L4940 SERIES VERY LOW DROP 1.5A REGULATORS ■ ■ ■ ■ ■ ■ PRECISE 5, 8.5, 10, 12V OUTPUTS LOW DROPOUT VOLTAGE (500mV Typ. at 1.5A) VERY LOW QUIESCENT CURRENT THERMAL SHUTDOWN SHORT CIRCUIT PROTECTION REVERSE POLARITY PROTECTION TO-220 TO-220FP D2PAK D2PAK/A DESCRIPTION The L4940 series of three terminal positive regulators is available in TO-220, TO-220FP and D2PAK packages and with several fixed output voltages, making it useful in a wide range of industrial and consumer applications. Thanks to its very low input/output voltage drop, these devices are particularly suitable for batteries powered equipment, reducing consumption and prolonging battery life. Each type employs internal current limiting, antisaturation circuit, thermal shut-down and safe area protection.
