The L4940 series of three terminal positive regulators is available in TO-220, TO-220FP and D
2PAK 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 andprolonging battery life. Each type employs internal current limiting, antisaturation circuit, thermal shut-down and safe area protection.

■ 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 protectionL4940
