Multiple voltage regulator with

power switches

TDA3682

Notes

1. The quiescent current is measured when RL = ∞ and VEN ≤ 0.8 V.

2. The dropout voltage of a regulator is the voltage difference between VP2 and Vo(REG).

3. The foldback current protection limits the dissipation power at short-circuit.

4. The dropout voltage of regulator 2 is the voltage difference between VSTCP and Vo(REG2) and depends on the load

current (see Fig.6).

5. The dropout voltage of regulator 2 is the voltage difference between VP2 and Vo(REG2) and depends on the load

current (see Fig.7).
