Preliminary specification
Very low dropout
voltage/quiescent current 8.5 V
voltage regulator
FEATURES Fixed 8.5 V, 100 mA 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 mA (see Fig.6) – Other
capacitors: 100 nF at 200 µA ≤ IREG ≤ 100 mA. Pin compatible 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
