Notes
1. Minimum operating voltage, only if VP has exceeded 7.5 V.
2. The quiescent current is measured in standby mode. Therefore, the battery input is connected to a low voltage
source and RL(REG) = ∞.
3. The voltage of the regulator sinks as a result of a supply voltage drop.
4. Only one band gap circuit is used as a reference for both regulator and Schmitt trigger for reset. Due to this a tracking
exists between the reset Schmitt trigger levels and the output voltage of the regulator.
5. The temperature coefficient of the internal resistor is 0.2%/K.
6.
The delay time can be calculated with the following formula:

ln
(---V----R----EV---G-R----E–---G--V----t--h--r---)
7. The battery output voltage will be equal or less than the output voltage of the regulator.
8. The drop-out voltage of the regulator is measured between VP and VREG.
9. At current limit, Il is held constant (behaviour according to dashed line in Fig.5).
10. The foldback current protection limits the dissipated power at short-circuit (see Fig.5).
11. The backup switch can deliver an additional current of 100 mA, guaranteed when the regulator is loaded with nominal
loads (IREG ≤ 150 mA).
