描述 Description

GENERAL DESCRIPTION
The TDA3661 is an adjustable voltage regulator with very low dropout voltage and quiescent current, which operates over a wide supply voltage range.
The IC is available as:
• TDA3661T: VP ≤ 33 V, −40 °C ≤ Tamb ≤ +85 °C and SO8 package (non-automotive)
• TDA3661AT: VP ≤ 45 V, −40 °C ≤ Tamb ≤ +125 °C and SO8 package (automotive).FEATURES
• Output adjustable from 1.5 V to VP, 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) < 38 Ω at IREG ≤ 25 mA
  – 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, t < 100 ms)
  – 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).
