2 / 16 page  2000 Feb 01 2 Philips Semiconductors Preliminary specification Low dropout voltage/quiescent current 10 V voltage regulator with enable TDA3676 FEATURES • Fixed 10 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) – Able to withstand voltages up to 18 V at the output (supply line may be short-circuited) – ESD protected for all pins – DC short-circuit safe to ground and VP of the regulator output – Temperature protection at Tj > 150 °C. GENERAL DESCRIPTION The TDA3676 is a fixed 10 V voltage regulator with very low dropout voltage and quiescent current, which operates over a wide supply voltage range. The IC is available as: • TDA3676T: VP ≤ 33 V, −40 °C ≤ Tamb ≤ +85 °C and SO8 package (non-automotive) • TDA3676AT: VP ≤ 45 V, −40 °C ≤ Tamb ≤ +125 °C and SO8 package (automotive).
