TDA3666

Very low dropout voltage/quiescent current 10 V voltage regulator

Philips Electronics 

Philips Semiconductors

Very low dropout voltage/quiescent current

10 V voltage regulator

Preliminary specification

TDA3666

FEATURES

• Fixed 10 V, 100 mA regulator

• 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) < 30 Ω at IREG ≤ 25 mA (see Fig.6)

– Other capacitors: 100 nF at 200 µA ≤ IREG ≤ 100 mA.

• Pin compatible family TDA3662 to TDA3666

• Protections:

– Reverse polarity safe (down to −25 V without high

reverse current)

– Negative transient of 50 V (RS = 10 Ω 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 (at Tj > 150 °C).

GENERAL DESCRIPTION

The TDA3666 is a fixed 10 V voltage regulator with a very

low dropout voltage and quiescent current, which operates

over a wide supply voltage range.

The IC is available as:

• TDA3666: VP ≤ 45 V; −40 °C ≤ Tamb ≤ +125 °C and

SO4 package (automotive)

• TDA3666AT: VP ≤ 45 V; −40 °C ≤ Tamb ≤ +125 °C and

SO8 package (automotive).
