part number with SGS 88719 printed on it.

The L487 is a monolithic integrated circuit in Pentawatt® package specially designed to provide a stabilized supply voltage for automotive and industrial electronic 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. The reset function makes the device particularly suited to supply microprocessor based systems: a pulse is available (after an externally programmable delay) to reset the microprocessor at power-on phase; at power-off, this pulse becomes low inhibiting the microprocessor.
