Philips Semiconductors
Low dropout voltage/quiescent current 5 V
voltage regulator with enable
Preliminary specification
TDA3674
FEATURES
Fixed 5 V, 100 mA regulator with enable function
Supply voltage range up to 33 V (45 V)
Very low quiescent current of 15 µA (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 µA IREG 100 mA.
Pin compatible family TDA3672 to TDA3676
Protections:
– Reverse polarity safe (down to 25 V without high
reverse current)
– Negative transient of 50 V (RS = 10 , 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).
GENERAL DESCRIPTION
The TDA3674 is a fixed 5 V voltage regulator with very low
dropout voltage and quiescent current, which operates
over a wide supply voltage range.
The IC is available as:
TDA3674T: VP 33 V, 40 °C Tamb +85 °C and
SO8 package (non-automotive)
TDA3674AT: VP 45 V, 40 °C Tamb +125 °C and
SO8 package (automotive).
