TDA3675
FEATURES
- Fixed 8.5 V, 100 m A regulator with enable function
- Supply voltage range up to 33 V (45 V)
- Very low quiescent current of 15 µA (typical value)
- Very low dropout voltage
- High ripple rejection
- Very high stability:
- Electrolytic capacitors: Equivalent Series Resistance (ESR) < 38 Ω at IREG ≤ 25 m A
- Other capacitors: 100 n F at 200 µA ≤ IREG ≤ 100 m A.
- Pin patible family TDA3672 to TDA3676
- Protections:
- Reverse polarity safe (down to
- 25 V without high reverse current)
- Negative transient of 50 V (RS = 10 Ω, t < 100 ms) QUICK REFERENCE DATA SYMBOL Supply VP supply voltage TDA3675T TDA3675AT Iq quiescent supply current VP = 14.4 V; IREG = 0 m A; VI(EN) = 5 V VI(EN) = 5 V 11.5 V ≤ VP ≤ 22 V; IREG = 0.5 m A 9.5 V ≤ VP ≤ 45 V; IREG = 0.5 m A VP = 14.4 V; 0.5 m A ≤ IREG ≤ 100 m A VREG(drop) dropout voltage VP = 8.0 V; IREG = 50 m A 8.16 8.08 8.08
