Overview

INTEGRATED CIRCUITS DATA SHEET TDA3668AT Very low dropout voltage/quiescent current 5 V regulator with overvoltage switch off Preliminary speciﬁcation Supersedes data of 1999 Nov 23 File under Integrated Circuits, IC01 2000 Feb 01 Philips Semiconductors Preliminary speciﬁcation Very low dropout voltage/quiescent current 5 V regulator with overvoltage switch off FEATURES • Fixed 5 V, 100 mA regulator • Supply voltage range up to 50 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 TDA3661 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) TDA3668AT – 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 regulator output – Temperature protection at Tj > 150 °C – Load dump protection, which will switch off VREG during load dump.
GENERAL DESCRIPTION The TDA3668AT is a fixed 5 V voltage regulator with a very low dropout voltage and quiescent current, which operates over a wide supply voltage range.
The regulator should use a supply voltage of VP ≤ 50 V.
It has a temperature range of −40 °C ≤ Tamb ≤ +125 °C, and it is available as an automotive version in an SO8 package.
