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. Operating DC supply voltage range 5.6V to 31V Low dropout voltage Low quiescent current consumption Reset circuit sensing of output voltage down to 1V Programmable reset pulse delay with external capacitor Programmable watchdog(a) timer with exte...
