Description  
The A6300 offers a high level of integration by combining  
voltage regulation and voltage monitoring. The voltage  
regulator has a low dropout ( typ. 380 mV at 100 mA )  
and a low quiescent current (100 µA). The quiescent  
current increases only slightly in dropout prolonging  
battery life. Built-in protection includes a positive transient  
absorber for up to 60 V (load dump) and the ability to  
survive an unregulated input voltage of –20 V (reverse  
battery). The INPUT may be connected to ground or a  
reverse voltage without reverse current flow from the  
OUTPUT to the INPUT. Upon the OUTPUT voltage rising  
above VTH, the reset output, whether RES or RES, will  
remain active (RES = 1, RES = 0) for an additional time  
of 50 ms. This allows the system voltage and the  
oscillator of the microprocessor to stabilize before they  
becomes fully active. When VOUTPUT falls below VTH, the  
reset output goes active. Threshold voltage can be  
obtained in different versions: 2 V, 2.4 V, 2.8 V, 3.5 V, 4 V.
