FEATURES
● Fixed 10 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) QUICK REFERENCE DATA SYMBOL Supply VP input supply voltage TDA3666 TDA3666AT Iq VREG quiescent supply current VP = 14.4 V; IREG = 0 mA 13 V ≤ VP ≤ 22 V; IREG = 0.5 mA 13 V ≤ VP ≤ 45 V; IREG = 0.5 mA VP = 14.4 V; 0.5 mA ≤ IREG ≤ 100 mA VREG(drop) dropout voltage VP = 9.3 V; IREG = 50 mA; Tamb ≤ 85 °C Voltage regulator output voltage 9.5 9.4 9.4 − 10 10 10 0.18 regulator on 3 3 − 14.4 14.4 15 PARAMETER CONDITIONS MIN.
