APPLICATION INFORMATION Introduction The NCP554/NCV554 are high performance dual output, 25 ma linear regulators suitable for post regulation and power sensitive batteryoperated applications. They feature 2.% 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. V, the dropout voltage is 25 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 PbFree package. Capacitor Selection The recommended input capacitor types are tantalum and aluminum electrolytic ranging from 4.7 F to F. It is especially required if the power source is located more than a few inches from the NCP554/NCV554. This capacitor 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 V in and GND traces should be sufficiently wide to minimize noise and unstable operation. For the adjustable output pin, C n ranges from pf and 1. nf. The output capacitor range is between 1. F and 22 F. For PCB layout considerations, place the capacitor close to the output pin and keep the leads short. Adjustable Output Operation The application circuit for the adjustable output version is shown in Figure 2. 2 is calculated based on the following equation: Vout2 1.25 V * 1 R2 R1 In order to maintain high accuracy on the adjustable output, R1 values should be < 3 k.
