Overview Dimensioning Information External Components input capacitor recommended compensation line influences. output capacitor necessary stability control loop. Stability guaranteed values within operating temperature range. small tolerances reset delay capacitance's spread delay capacitor temperature coefficient should taken into consideration. Circuit Description control amplifier compares reference voltage voltage that proportional output voltage drives base series transistor buffer. Saturation control function load current prevents oversaturation power element. component also number internal circuits protection against: Overload Overtemperature Reverse polarity
case externally scaled down output voltage reset adjust input falls below 1.35 external reset delay capacitor discharged reset generator. When voltage capacitor reaches lower threshold VDRL, reset signal occurs reset output held until upper threshold exceeded. reset threshold input connected GND, reset triggered output voltage typically 4.65
