APPLICATION INFORMATION
Introduction
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.
Capacitor Selection
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
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 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.
Adjustable Output Operation
The application circuit for the adjustable output version is
shown in Figure 2. V
out2
is calculated based on the following
equation:

In order to maintain high accuracy on the adjustable
output, R1 values should be < 30 kW.
