The part is designed for automotive environment, and thus can withstand up to 45V and 125°C temperature range. The output voltage is set at a fixed 5V, and the part is guaranteed to deliver at least 150mA. The SPX2969 provides multiple protection mechanisms, including overtemperature and over-current conditions. The part has a built-in reset circuit to monitor when the output voltage is below 4.65V. The reset voltage threshold can be programmed down to 3.5V using an external resistor voltage divider, while the reset timing can be programmed via an external capacitor. A built in comparator compares the signal of the pin SI, normally fed by a voltage divider from the input voltage, with the reference and gives an early warning on the pin SO. Both the sense output and the reset output delay signals contain integrated 20kOhm pull up resistors. The part is available in three package types: 8 Pin and 14 Pin nSOIC or 20 Pin wSOIC packages.

Note 2: Drop voltage = VI - VQ measured when the output voltage has dropped 100mV from the nominal value obtained at 13.5V input. Note 3: The reset threshold VRT can be decreased via an external voltage divider connected to the RADJ. In this case the reset condition is reached if VQ < VRT and VRADJ < VRAQDJ, TH .

Using a resistor of approximately 1Ω in series with CI, the oscillating circuit consisting of input inductivity and input capacitance can be damped. The output capacitor CQ is necessary for the stability of the regulating circuit. Stability is guarantted at values ≥ 10µF and an ESR ≤ 10Ω within the operating temerature range. For small tolerances of the reset delay the spread of the capacitance of the delay capacitor and its temperature coefficient should be noted.
