Description

L4995 is a family of monolithic integrated 5 V

voltage regulators with a low drop voltage at

currents of up to 500 mA, available in both 12 and

24 pin packages.

The output voltage regulating element consists of

a p-channel MOS and regulation is performed

regardless of input voltage transients of up to 40V.

The high precision of the output voltage is

obtained using a pre-trimmed reference voltage.

The L4995 family is protected against short circuit

and overtemperature protection switches off the

devices in the case of extremely high power

dissipation. The L4995 integrates the watchdog,

enable and externally programmable reset

circuits. The L4995A features the externally

programmable reset and enable. Finally the

L4995R features the externally programmable

reset.

The combination of such features makes this

device particularly flexible and suitable to supply

microprocessor systems in automotive

applications.
