General description

The TDA3663 is a fixed 3.3 V voltage regulator with a very low dropout voltage and quiescent current, which operates over a wide supply voltage range.

Features

■ Fixed 3.3 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 (at Tj > 150 °C)
