Description  
Quiescent current  
Iqn  
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.  
1. Typical value with regulator disabled  
Operating DC supply voltage range 5.6V to  
31V  
The output voltage regulating element consists of  
a p-channel MOS and regulation is performed  
regardless of input voltage transients of up to 40V.  
Low dropout voltage  
Low quiescent current consumption  
Reset circuit sensing of output voltage down to  
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.  
1 V  
Programmable reset pulse delay with external  
capacitor  
Programmable watchdog(a) timer with external  
capacitor  
Thermal shutdown and short circuit protection  
Wide temperature range (Tj = -40 °C to 150 °C)  
Enable(a) input for enabling/disabling the  
voltage regulator  
The combination of such features makes this  
device particularly flexible and suitable to supply  
microprocessor systems in automotive  
applications.
