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.
