General description

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

■ Fixed 5 V, 100 mA regulator

■ Supply voltage range up to 45 V

■ Very low quiescent current of 15 µA (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

◆ Temperature protection (Tj > 150 °C)
