TDA3664/N1,135

The TDA3664/N1 is a fixed Voltage Regulator with very low dropout voltage/quiescent current, which operates over a wide supply voltage range. This is a fixed 5V regulator which can deliver output currents up to 100mA. The regulator is intended for portable, mains and telephone applications. To increase the lifetime of batteries, a specially built-in clamp circuit keeps the quiescent current of this regulator very low, also in dropout and full load conditions. The regulator remains operational down to very low supply voltages, below which it switches off. A temperature protection is included, which switches the regulator output off at IC temperatures above 150 °C.

• Very low quiescent current of 15mA (typical value)
• Very low dropout voltage
• High ripple rejection
• Reverse polarity safe (down to -25V without high reverse current)
• Negative transient of 50V
• Able to withstand voltages up to 18V at output (supply line may be short-circuited)
• DC short-circuit safe to ground and VP of regulator output
• Temperature protection
