INTEGRATED CIRCUITS DATA SHEET TDA3666 Very low dropout voltage/quiescent current 10 V voltage regulator Preliminary specification File under Integrated Circuits, IC01 2000 Apr 26 Philips Semiconductors Preliminary specification Very low dropout voltage/quiescent current 10 V voltage regulator 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.

TYP.
TDA3666 – Able to withstand voltages up to 18 V at the output (supply line may be short-circuited) – ESD protection on all pins – DC short-circuit safe to ground and VP of the regulator output – Temperature protection (at Tj > 150 °C).
GENERAL DESCRIPTION The TDA3666 is a fixed 10 V voltage regulator with a very low dropout voltage and quiescent current, which operates over a wide supply voltage range.
The IC is available as: • TDA3666: VP ≤ 45 V; −40 °C ≤ Tamb ≤ +125 °C and SO4 package (automotive) • TDA3666AT: VP ≤ 45 V; −40 °C ≤ Tamb ≤ +125 °C and SO8 package (automotive).
