production data
Features
• Precise 5, 8.5, 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 and D²PAK
packages and with several fixed output voltages,
making it useful in a wide range of industrial and
consumer applications. Thanks to their very low
input/output voltage drop, these devices are
particularly suitable for battery-powered
equipment, reducing consumption and prolonging
battery-life. Each type employs internal current
limiting, anti-saturation circuit, thermal shutdown
and safe area protection.
