Product Summary
The L4940V5 is a three terminal positive regulator. The L4940V5 is available in TO-220 and D2PAK package 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, the device is particularly suitable for battery powered equipments, reducing consumption and prolonging battery life. Each type employs internal current limiting, antisaturation circuit, thermal shut-down and safe area protection.
Parametrics
L4940V5 absolute maximum ratings: (1)VI, Forward Input Voltage: 30 V; (2)VIR, Reverse Input Voltage VO = 5 V RO = 100 W: -15 V; (3)IO, Output Current: Internally Limited; (4)Ptot, Power Dissipation: Internally Limited; (5)Tj, Tstg, Junction and Storage Temperature: -40 to 150℃.
Features
L4940V5 features: (1)Precise 5 V, 8.5 V, 10 V, 12 V outputs; (2)Lowdropout voltage(500 mV typ at 1.5A); (3)Verylow quiescentcurrent; (4)Thermal shutdown; (5)Short circuit protection; (6)Reversepolarity protection.
