TDA3664

Very low dropout voltage/quiescent current 5 V voltage regulator


The TDA3664 is a fixed voltage regulator with very low dropout voltage/quiescent current, which operates over a wide supply voltage range.

The regulator is available as:

  • TDA3664: SO4 package
  • TDA3664AT: SO8 package
  • TDA3664TT: TSSOP8 package

Features and benefits

  • Fixed 5 V, 100 mA regulator
  • Supply voltage range up to 45 V
  • Very low quiescent current of 15 uA (typical value)
  • Very low dropout voltage
  • High ripple rejection
  • 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
