Product data sheet
1. 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.
2. Features
s Fixed 3.3 V, 100 mA regulator
s Supply voltage range up to 45 V
s Very low quiescent current of 15 µA (typical value)
s Very low dropout voltage
s High ripple rejection
s Protections:
x Reverse polarity safe (down to −25 V without high reverse current)
x Negative transient of 50 V (R_S = 10 Ω, t < 100 ms)
x Able to withstand voltages up to 18 V at the output (supply line may be
short-circuited)
x ESD protection on all pins
x DC short-circuit safe to ground and V_P of the regulator output
x Temperature protection (at T_j > 150 °C)
