Preliminary specication
Very low dropout voltage/quiescent current
5 V voltage regulator
TDA3664
FEATURES
General
Fixed 5 V, 100 mA regulator
Supply voltage range up to 33 V (45 V)
Very low quiescent current of 15 A (typical value)
Very low dropout voltage
High ripple rejection
Very high stability:
– Electrolytic capacitors: Equivalent Series Resistance
(ESR) <38
at IREG ≤ 25 mA
– Other capacitors: 100 nF at 200
A ≤ IREG ≤ 100 mA.
Pin compatible family TDA3662 up to TDA3666.
Protections
Reverse polarity safe (down to 25 V without high
reverse current)
Negative transient of 50 V (RS =10 and 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 (Tj > 150 °C).
GENERAL DESCRIPTION
The TDA3664 is a fixed 5 V 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 (automotive)
TDA3664T: SO8 package (non-automotive)
TDA3664AT: SO8 package (automotive)
TDA3664TT: TSSOP8 package (automotive).
Automotive: VP ≤ 50 V and 40 °C ≤ Tamb ≤ +125 °C.
Non-automotive: VP ≤ 22 V and 40 °C ≤ Tamb ≤ +85 °C.
