Product overview
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.
