TDA3672
FEATURES
- Fixed 3.0 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) < 30 Ω at IREG ≤ 25 m A (see Fig.6)
- 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 and t < 100 ms) QUICK REFERENCE DATA SYMBOL Supply VP Iq supply voltage quiescent supply current regulator on VP = 14.4 V; IREG = 0 m A; VI(EN) = 5 V 7.5 ≤ VP ≤ 22 V; IREG = 0.5 m A 5.5 V ≤ VP ≤ 45 V; IREG = 0.5 m A VREG(drop) dropout voltage VP = 2.8 V; IREG = 50 m A; Tamb ≤ 85 °C 3
