TDA3664AT/N1/N,118

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P16
1. 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
2. Features
n Fixed 5 V, 100 mA regulator
n Supply voltage range up to 45 V
n Very low quiescent current of 15 µA (typical value)
n Very low dropout voltage
n High ripple rejection
n Protections:
u Reverse polarity safe (down to −25 V without high reverse current)
u Negative transient of 50 V (R
S
=10Ω; t < 100 ms)
u Able to withstand voltages up to 18 V at the output (supply line may be
short-circuited)
u ESD protection on all pins
u DC short-circuit safe to ground and V
P
of the regulator output
u Temperature protection (T
