7 / 16 page 1998 May 07 7 Philips Semiconductors Product specification Multiple voltage regulator with battery detection TDA3606A Notes 1. Minimum operating voltage, only if VP has exceeded 7.6 V. 2. The quiescent current is measured in standby mode. So, the battery input is connected to a low voltage source and RL = ∞. 3. The voltage of regulator sinks as a result of a supply voltage drop. 4. The delay time can be calculated with the following formula: 5. Battery output voltage will be equal or less than the output voltage of regulator. 6. The drop-out voltage of regulator is measured between VP and VREG. 7. At current limit, Iclr is held constant (behaviour according to dashed line in Fig.4). 8. The foldback current protection limits the dissipated power at short-circuit (see Fig.4).
