A voltage regulator is an electronic device that is used to maintain a constant voltage level, regardless of changes in load or input voltage.
It does this by adjusting the output voltage so that it remains within a specified range.
This helps to ensure that the voltage supplied to a device remains within the acceptable range, even under varying conditions such as changes in temperature or load.
Part Number: L487
Function: Very Low Drop 5V Voltage Regulator
Package: Pentawatt 5 Pin Type
The L487 is a monolithic integrated circuit in pentawatt package specially designed to provide a stabilized supply voltage for automotive and industrial electronics system.
Thanks to its very low voltage drop in automotive applications the L487 can work correctly even during the cranking phase, when the battery voltage could fall as low as 6V. Furthermore, it incorporates a complete range of protection circuits against the dangerous overvoltages always present on the battery rail of the car.
1. PRECISE OUTPUT VOLTAG E (5V ± 4% )
2. VERY LOW DROPOUT VOLTAGE
3. OUTPUT CURRENT IN EXCESS OF 500mA
4. POWER-ON, POWER-OF F INFOR MATION ( RESET FUNCTI ON)
5. +80/–80V LOAD DUMP PROTECTION
6. OVERVOLTAGE AND REVERSE VOLTAGE PROTECTION
