The maximum operating voltage is 45 V. The output is able to drive 150 mA load. It is short circuit protected and the thermal shutdown switches the output off if the junction temperature is in excess of 150 °C. A reset signal is generated for an output voltage of VQ < 4.65 V. The reset threshold voltage can be decreased by external connection of a voltage divider. P/PG-DSO-20-1,-6,-7,-9,-14,The reset delay time can be set by an external capacitor. Reset and sense output have integrated pull-up resistors. If the integrated resistors are not desired TLE 4279 can be used. It is also possible to supervise the input voltage by using an integrated comparator to give a low voltage warning.

Data Sheet 4 Rev. 2.4, 2007-03-20 TLE 4269 Circuit Description The control amplifier compares a reference voltage, made highly accurate by resistance balancing, with a voltage proportional to the output voltage and drives the base of the series PNP transistor via a buffer. Saturation control as a function of the load current prevents any over-saturation of the power element. The reset output RO is in high-state if the voltage on the delay capacitor CD is greater or equal VUD. The delay capacitor CD is charged with the current ID for output voltages greater than the reset threshold VRT. If the output voltage gets lower than VRT (‘reset condition’) a fast discharge of the delay capacitor CD sets in and as soon as VD gets lower than VLD the reset output RO is set to low-level. The time gap for the delay capacitor discharge is the reset reaction time tRR. The reset threshold VRT can be decreased via an external voltage divider connected to the pin RADJ. In this case the reset condition is reached if VQ < VRT and VRADJ < VRAQDJ, TH. Dimensioning the voltage divider (Figure 5) according to: VTHRES = VRADJ,TH × (RADJ1 + RADJ2) / RADJ2, (1) the reset threshold can be decreased down to 3.5 V. If the reset-adjust-option is not needed the RADJ-pin should be connected to GND causing the reset threshold to go to its default value (typ. 4.65 V). 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. It is also possible to superwise another voltage e.g. of a second regulator, or to build a watchdog circuit with few external components. Application Description The input capacitor CI is necessary for compensating line influences. Using a resistor of approx. 1 Ω 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 guaranteed at values ≥ 10 µF and an ESR ≤ 10 Ω within the operating temperature range. For small tolerances of the reset delay the spread of the capacitance of the delay capacitor and its temperature coefficient should be noted.
