Application

The IC regulates an input voltage VI in the range of 5.5 V < VI < 40 V to a nominal outputvoltage of VQ = 5.0 V. A reset signal is generated for an output voltage of VQ < VRT (typ.4.5 V). The reset delay can be set with an external capacitor. The device has two logicinputs. A voltage of VE2 > 4.0 V given to the E2-pin (e.g. by ignition) turns the device on.Depending on the voltage on pin E6 the IC may be hold in active-state even if VE2 goesto low level. This makes it simple to implement a self-holding circuit without externalcomponents. When the device is turned off, the output voltage drops to 0 V and currentconsumption tends towards 0 µA.

Design Notes for External Components

The input capacitor CI is necessary for compensation of line influences. The resonantcircuit consisting of lead inductance and input capacitance can be damped by a resistorof approx. 1 Ω in series with CI. The output capacitor is necessary for the stability of theregulating circuit. Stability is guaranteed at values of ≥ 22 µF and an ESR of ≤ 3 Ω withinthe operating temperature range.

Circuit Description

The control amplifier compares a reference voltage, which is kept highly accurate byresistance adjustment, to a voltage that is proportional to the output voltage and drivesthe base of the series transistor via a buffer. Saturation control as a function of the loadcurrent prevents any over-saturating of the power element.

The reset output RO is in high-state if the voltage on the delay capacitor CD is greater orequal VUD. The delay capacitance CD is charged with the current ID for output voltagesgreater than the reset threshold VRT. If the output voltage gets lower than VRT a fastdischarge of the delay capacitor CD sets in and as soon as VCD gets lower than VLD thereset output RO is set to low-level (see Figure 6). The reset delay can be set within widerange by dimensioning the capacitance of the external capacitor.
