Product speciﬁcation

Multiple output voltage regulator

TDA3602

When the device is in the on mode, it will switch back to the reset mode when Vsc rises to 2 V, or when the supply voltage

drops below 7.3 V.

When VREG3 drops below 3 V, the device will return to the power off mode, regardless of the condition the device was in.

LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134).

Note

1. Vbu (pin 8) supplied by VP2 with a 100 Ω series resistor and IREG3 < 10 mA.

THERMAL RESISTANCE

CHARACTERISTICS
