NXP Semiconductors
Very low dropout voltage/quiescent current 5 V voltage regulator
7. 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, TSSOP8 and SO4 packages. The regulator is intended for
portable, mains and telephone 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.
A temperature protection is included, which switches the regulator output off at
IC temperatures above 150 °C.

11. Application information
11.1 Noise
The output noise is determined by the value of the output capacitor (see Table 7).

[1] Measured at a bandwidth of 10 Hz to 100 kHz
11.2 Stability
For stable operation:
• The maximum output capacitor ESR should not exceed 22 Ω (worst-case) and for the
minimum ESR, see Table 8.
• The ESR of the output capacitor is limited.
• See Table 8 for the minimum ESR values of the output capacitor, at Tamb given the
load and output capacitance.

Very low dropout voltage/quiescent current 5 V voltage regulator
Remark: In the event of using different types of capacitors, a minimum ESR needs to
be created by using an additional resistor that is placed in series with the output
capacitor, see Figure 4.
• It is recommended not to use below 1 mA output current because of reduced phase
margin.

11.3 Application circuits
The maximum output current of the regulator equals:
150 – Tamb
150 – Tamb
---------------------------------------------------------
Rth( j – a) × (VP – VREG
IREG(max)
=
=
(mA)
-----------------------------------
100 × (VP – 5)
)
When Tamb = 21 °C, the maximum output current equals 140 mA at VP =14 V.
The total thermal resistance of the TDA3664 (SOT223-1 package) can be decreased to
lower values when pin 4 and body of the package are soldered to the printed-circuit board.
11.3.1 Application circuit with backup function
Sometimes, a backup function is needed to supply, for example, a microcontroller for a
short period of time when the supply voltage spikes to 0 V (or even −1 V).
This function can easily be built with the TDA3664 by using a large output capacitor. When
the supply voltage is 0 V (or −1 V), only a small current will flow into pin REG from this
large output capacitor (a few µA).
The application circuit is given in Figure 4.

(4) For reliable operation, it is recommended to have a minimum ESR of 3 Ω of the output
capacitor total (see Figure 4 above) and to have a stable application independent of load
current, temperature or output capacitance.
