The ground plane on the top side of the PCB acts like a heat spreader. 7. Functional description The TDA3663 is a fixed 3.3 V regulator which can deliver output currents up to 100 mA. The regulator is available in SO8 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 device remains operational down to very low supply voltages and below this voltage it switches off. A temperature protection circuit is included which switches off the regulator output at a junction temperature above 150 °C. 8.

Application information 11.1 Noise The output noise is determined by the value of the output capacitor. The noise figure is measured at a bandwidth of 10 Hz to 100 kHz (see Table 7). Table 7: Noise figures Output current IREG (mA) Noise figure (µV) C2 = 10 µF C2 = 47 µF C2 = 100 µF 0.5 550 320 300 50 650 400 400 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. 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 is 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 – 3.3 ) R th ( j – a ) × ( V P – V REG ) When Tamb = 21 °C and VP = 14 V the maximum output current equals 116 mA. The total thermal resistance of the TDA3663 can be decreased from 155 K/W to 30 K/W for the SO8 version. For the SO4 version it can be decreased from 100 K/W to 25 K/W when GND pins 2 and 4 of the package are soldered to the printed-circuit board. TDA3663_6 Product data sheet © NXP B.V. 2007.

Rev. 06 — 26 June 2007 6 of 15 TDA3663 NXP Semiconductors Very low dropout voltage/quiescent current 3.3 V voltage regulator 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 TDA3663 by using an output capacitor with a large value. When the supply voltage is 0 V (or −1 V), only a small current will flow into pin REG from this output capacitor (a few µA). The application circuit is given in Figure 4. VP 1 C1(1) 1 µF VREG = 3.3 V 3 + ESR > 3 Ω TDA3663 + C2(2) 2, 4 014aaa088 (1) C1 is optional (to minimize supply noise only). (2) C2 ≤ 4700 µF. (3) For reliable operation, it is recommended to have a minimum ESR of 3 Ω of the output capacitor total and to have a stable application independent of load current, temperature or output capacitance.
