With an input voltage range of 2.75 V to 42 V and ultra low quiescent of only 5.5 µA, the regulator is perfectly suitable for automotive or any other supply systems connected permanently to the battery. The TLS805B1LDV33 is the fixed 3.3 V output version with an accuracy of 2 % and output current capability up to 50 mA. The new regulation concept implemented in TLS805B1 combines fast regulation and very good stability while requiring only a small ceramic capacitor of 1 μF at the output. Data Sheet www.infineon.com/power 1 Rev. 1.1 2016-12-20 TLS805B1LDV33 Ultra Low Quiescent Current Linear Voltage Regulator Overview The tracking region starts already at input voltages of 2.75 V (extended operating range). This makes the TLS805B1 also suitable to supply automotive systems that need to operate during cranking condition. Internal protection features like output current limitation and overtemperature shutdown are implemented to protect the device against immediate damage due to failures like output short circuit to GND, over-current and over-temperature. The device can be switched on and off by the Enable feature. When the device is switched off, the current consumption is typically less than 1 µA.

Data Sheet 9 Rev. 1.1 2016-12-20 TLS805B1LDV33 Ultra Low Quiescent Current Linear Voltage Regulator Block Description and Electrical Characteristics 5 Block Description and Electrical Characteristics 5.1 Voltage Regulation The output voltage VQ is divided by a resistor network. This fractional voltage is compared to an internal voltage reference and the pass transistor is driven accordingly. The control loop stability depends on the output capacitor CQ, the load current, the chip temperature and the internal circuit structure. To ensure stable operation, the output capacitor’s capacitance and its equivalent series resistor ESR requirements given in “Functional Range” on Page 8 have to be maintained. For details see the typical performance graph Output Capacitor Series Resistor ESR(CQ ) versus Output Current IQ on Page 14. Since the output capacitor is used to buffer load steps, it should be sized according to the application’s needs. An input capacitor CI is not required for stability, but is recommended to compensate line fluctuations. An additional reverse polarity protection diode and a combination of several capacitors for filtering should be used, in case the input is connected directly to the battery line. Connect the capacitors close to the regulator terminals. In order to prevent overshoots during start-up, a smooth ramping up function is implemented. This ensures almost no overshoots during start-up, mostly independent from load and output capacitance. Whenever the load current exceeds the specified limit, for example in case of a short circuit, the output current is limited and the output voltage decreases. The overtemperature shutdown circuit prevents the IC from immediate destruction under fault conditions (for example output continuously short-circuit) by switching off the power stage. After the chip has cooled down, the regulator restarts. This oscillatory thermal behaviour causes the junction temperature to exceed the maximum rating of 150°C and can significantly reduce the IC’s lifetime.
