Line Transient Response for Vout2 http://onsemi.com 8 NCP5504, NCV5504 APPLICATION INFORMATION Introduction will reduce device sensitivity and enhance the output transient response time. The PCB layout is very important and in order to obtain the optimal solution, the Vin and GND traces should be sufficiently wide to minimize noise and unstable operation. For the adjustable output pin, Cn ranges from 200 pF and 1.0 nF. The output capacitor range is between 1.0 mF and 22 mF. For PCB layout considerations, place the capacitor close to the output pin and keep the leads short. The NCP5504/NCV5504 are high performance dual output, 250 mA linear regulators suitable for post regulation and power sensitive battery−operated applications. They feature ±2.0% accuracy over the operating temperature range. With one fixed output voltage at 3.3 V, and one adjustable output voltage ranging from 1.25 V to 5.0 V, the dropout voltage is 250 mV typical. Additional features, such as an architecture that allows for low noise on the fixed output without a bypass capacitor, provides for an attractive LDO solution for audio visual equipment, instrumentation, computing and networking applications, and automotive electronics. It is thermally robust and is offered in a 5 pin DPAK Pb−Free package. Adjustable Output Operation The application circuit for the adjustable output version is shown in Figure 2. Vout2 is calculated based on the following equation: ǒ Capacitor Selection Ǔ Vout2 + 1.25 V * 1 ) R2 R1 The recommended input capacitor types are tantalum and aluminum electrolytic ranging from 4.7 mF to 100 mF. It is especially required if the power source is located more than a few inches from the NCP5504/NCV5504. This capacitor In order to maintain high accuracy on the adjustable output, R1 values should be < 30 kW.
