1 / 23 page February 2008 Rev 10 1/23 23 L4940xx Very low drop 1.5 A regulator Features ■ Precise 5, 8.5, 10, 12 V outputs ■ Low dropout voltage (450 mV typ. at 1 A) ■ Very low quiescent current ■ Thermal shutdown ■ Short circuit protection ■ Reverse polarity protection 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. D2PAK TO-220FP TO-220 Table 1.
