Preliminary speciﬁcation

Very low dropout voltage/quiescent current

8.5 V voltage regulator

TDA3665

CHARACTERISTICS

VP = 14.4 V; Tamb =25 °C; measured with test circuit (see Fig.4); unless otherwise speciﬁed.

Notes

1. The regulator output will follow VP if VP <VREG +VREG(drop).

2. Limiting values as applicable for both device types: VP ≤ 45 V and −40 °C ≤ Tamb ≤ +125 °C.
