L4941：Very low drop 1A regulator
The L4941 is a three terminal 5V positive regulators available in TO-220 and DPAK packages, 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 battery powered equipments, reducing consumption and prolonging battery life. It employs internal current limiting, antisaturation circuit, thermal shut-down and safe area protection.
Key Features
- Low dropout voltage (450mV typ. at 1A)
- Thermal shutdown
- Very low quiescent current
- Reverse polarity protection
- Short circuit protection
