1.5 A very low drop voltage regulator IC
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.
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
LDO controller, 7 V ... 17 V, 8.5 Vout, 1.5 Aout, TO-220-3
