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. TDA3664_7 Product data sheet © NXP B.V. 2007. All rights reserved.

Rev. 07 — 25 June 2007 6 of 16 TDA3664 NXP Semiconductors 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. Table 8: Minimum ESR values required IREG (mA) max C2 = 100 nF C2 = 1 µF C2 = 10 µF C2 = 100 µF 1 >0Ω > 1.5 Ω > 2.5 Ω >0Ω 5 >1Ω > 0.5 Ω >1Ω >0Ω 10 >0Ω > 0.5 Ω >4Ω >0Ω 100 >0Ω > 0.5 Ω >4Ω >0Ω 11.3 Application circuits The maximum output current of the regulator equals: 150 – T amb 150 – T amb I REG ( max ) = --------------------------------------------------------- = ------------------------------------ ( mA ) 100 × ( V P – 5 ) R th ( j – a ) × ( V P – V REG ) 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.
