• Manufacturer Part Number: TDA3664T
• Description: Very low dropout voltage/quiescent current 5 V voltage regulator
• Manufacturer: PHILIPS [NXP Semiconductors]

Philips Semiconductors
FUNCTIONAL DESCRIPTION
The TDA3664 is a fixed 5 V regulator which can deliver
output currents up to 100 mA. The regulator is available in
SO8 and SOT223 packages. The regulator is intended for
portable, mains, telephone and automotive applications.
To increase the lifetime of batteries, a specially built-in
clamp circuit keeps the quiescent current of this regulator
very low, also in dropout and full load conditions.
The regulator remains operational down to very low supply
voltages, below which it switches off.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).

A temperature protection is included, which switches the
regulator output off at IC temperatures above 150 C.
A new output structure guarantees the stability of the
regulator with an ESR up to 38 . This is very attractive as
the ESR of an electrolytic capacitor increases strongly at
low temperatures (no expensive tantalum capacitor
required).
