TDA3665
FEATURES
- Fixed 8.5 V, 100 m A regulator
- 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 TDA3662 to TDA3666
- Protections:
- Reverse polarity safe (down to
- 25 V without high reverse current)
- Negative transient of 50 V (RS = 10 Ω and t < 100 ms)
- Able to withstand voltages up to 18 V at the output (supply line may be short-circuited) QUICK REFERENCE DATA SYMBOL Supply VP supply voltage TDA3665 TDA3665AT Iq VREG quiescent supply current VP = 14.4 V; IREG = 0 m A 11.5 V ≤ VP ≤ 22 V; IREG = 0.5 m A 11.5 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 = 7.9 V; IREG = 50 m A; Tamb ≤ 85 °C Voltage regulator output voltage 8.08 8.0 8.0
