NXP Semiconductors TDA3668AT
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.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.
