FEATURES
● Fixed 3.3 V, 100 mA 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 mA – Other capacitors: 100 nF at 200 µA ≤ IREG ≤ 100 mA.
● Pin compatible 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 TDA3673T TDA3673AT Iq quiescent supply current VP = 14.4 V; IREG = 0 mA; VI(EN) = 5 V 8 V ≤ VP ≤ 22 V; IREG = 0.5 mA 6 V ≤ VP ≤ 45 V; IREG = 0.5 mA 0.5 mA ≤ IREG ≤ 100 mA; VP = 14.4 V VREG(drop) dropout voltage VP = 3.1 V; IREG = 50 mA; Tamb ≤ 85 °C regulator on 3 3 − 14.4 14.4 15 PARAMETER CONDITIONS MIN.
