Philips Semiconductors
Preliminary specification
Very low dropout voltage/quiescent
current 5 V voltage regulator
TDA3664
CHARACTERISTICS
VP = 14.4 V; Tamb =25 °C; see Fig.4; unless otherwise specified.
Notes
1. The regulator output will follow VP if VP <VREG +VREG(drop)
2. TDA3664T: VP ≤ 22 V; −40 °C ≤ Tamb ≤ 85 °C.
