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.
FEATUREs
■ Output adjustable from 1.5 V to VP, 100 mA regulator
■ Supply voltage range up to 45 V
■ Very low quiescent current of 15 µA (typical value)
■ Very low dropout voltage
■ 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)
