TDA3661

Very low dropout voltage/quiescent current adjustable voltage

regulator

Rev. 05 — 28 June 2005

Product data sheet

1. General description

The TDA3661 is an adjustable voltage regulator with very low dropout voltage and

quiescent current, which operates over a wide supply voltage range.

2. Features

Output adjustable from 1.5 V to V

, 100 mA regulator

Supply voltage range up to 45 V

Very low quiescent current of 15

µA

(typical value)

Very low dropout voltage

Protections:

Reverse polarity safe (down to

−25

V without high reverse current)

Negative transient of 50 V (R

= 10

Ω,

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 V

of the regulator output

Temperature protection (at T

> 150

°C)
