The IC regulates an input voltage VI in the range of 2.7 V VI 18 V to an adjustable output voltage of 1.2 V to 5.25 V with a precision of 3 %. The TLS202A1 is especially designed for applications requiring very low standby currents, e.g. with a permanent connection to preregulators like DCDC converters. The regulator is not designed to operate with a direct connection to the battery. The device is available in a very small surface mounted PGSCT595 package. The device is designed for the harsh environment of automotive applications. Therefore it is protected against overload, short circuit and overtemperature conditions by the implemented output current limitation and the overtemperature shutdown circuit. The TLS202A1 can be also used in all other applications requiring a stabilized voltage of 1.2 V to 5.25 V. Choosing External Components The input capacitor CI is recommended for compensating line influences. The output capacitor CQ is necessary for the stability of the regulating circuit. Stability is guaranteed at values specified in "Functional Range" on Page 6 within the whole operating temperature range.

Data Sheet 6 Rev. 1.0, 2015-06-22 TLS202A1 Voltage Regulator 5 Voltage Regulator 5.1 Description Voltage Regulator The output voltage VQ is controlled as follows: It is divided by the external resistor divider and this fraction is distributed to the ADJ Pin. The Voltage at the ADJ is then compared to an internal reference and drives the pass transistor accordingly. By connecting the ADJ pin directly to the output Q the device will regulate to its reference voltage. In this case a minimum load resistance of less than 1 M needs to be ensured for stability reasons. The control loop stability depends on the output capacitor CQ, the load current, the chip temperature and the circuit design. To ensure stable operation, the requirements for output capacitance and equivalent series resistance ESR, given in "Functional Range" on Page 6, have to be maintained. For details see also the typical stability graph of ESR versus load current on Page 12. As the output capacitor also has to buffer load steps it should be sized according to the needs of the application. An input capacitor CI of at least 220 nF is recommended to compensate line influences. Connect the capacitors close to the terminals of the component. In case the load current is above the specified limit, e.g. in case of a short circuit, the output current limitation limits the current. The output voltage is therefore decreasing at the same time. The overtemperature shutdown circuit prevents the IC from immediate destruction under fault conditions (e.g. output continuously short-circuited) by switching off the power stage. After the chip has cooled down, the regulator restarts. This leads to an oscillatory behavior of the output voltage until the fault is removed. However, junction temperatures above 150 C are outside the maximum ratings and therefore significantly reduce the IC's lifetime.
