An input voltage up to 42 V is P-TO263-5-1 regulated to VQ,nom = 5.0 V. The device is designed to supply μ-controllers in the severe environment of automotive applications. Therefore it is protected against overload, short circuit and over temperature conditions. Of course the TLE 4290 can been used also in all other applications, where a stabilized 5 V voltage is required.

Connecting the regulator to a battery voltage at first the power good signal remains LOW. When the output voltage has reached the higher threshold VQ,pgt-i the power good output remains still LOW for the power good delay time trd. Afterwards the power good output turns HIGH. The delay time can be set by the user with an external capacitor at pin D according to the requirements of the application. The Power Good circuitry supervises the output voltage. In case VQ falls below the lower Power Good switching threshold VQ,pgt-d the PG output is set LOW after the Power Good reaction time. The Power Good LOW signal is generated down to an output voltage VQ to 1 V. A LOW signal at the Power Good pin informs that the battery was lost and memory is no longer valid. The feature should be used in combination with a microcontroller with internal reset.

A resistor of approx. 1 Ω in series with CI, can damp the LC of the input inductivity and the input capacitor. The TLE 4290 requires an output capacitor of at least 22 μF with an ESR below 5 Ω for stability. Power Good The Power Good pin informs e.g. the micro-controller in case the output voltage has fallen below a threshold of typ. 3.65 V. When the battery voltage is supplied the Power Good signal indicates a loss of memory due to missing power. After the Memory Good switching threshold is reached the Power Good output remains low for the Power Good delay time. This time can be set by the user with an external capacitor at pin D according to the requirements of the application, e.g. the time until the microcontroller is initialized and ready to receive any information. Data Sheet 8 Rev. 1.7, 2007-03-20 TLE 4290 The power good circuit supervises the output voltage. In case VQ falls below the Power Good switching threshold the Power Good output PG is set LOW after the power good reaction time. The power good LOW signal is generated down to an output voltage VQ to 1 V. A LOW signal at the power good pin informs that the battery was lost and memory is no longer valid. The feature should only be used in combination to a microcontroller with internal reset. For the power good delay time after the output voltage of the regulator is above the reset threshold, the reset signal is set High again. The reset delay time is defined by the reset delay capacitor CD at pin D. The Power Good delay time is defined by the charging time of an external delay capacitor CD.

It is typically 0.5 μs for delay capacitor of 47 nF. For other values for CD the reaction time can be estimated using the following equation: trr = 10 ns/nF × CD (2) The Power Good output is an open collector output. It requires externally a pull-up resistor of at least 5 kΩ to Q.
