NCP5661

Low Output Voltage,

Ultra−Fast 1.0 A Low Dropout

Linear Regulator with Enable

The NCP5661 is a high performance, low dropout linear regulator

designed for high power applications that require up to 1.0 A current.

It is offered in both fixed and adjustable output versions. With output

voltages as low as 0.9 V and ultra−fast response times for load

transients, the NCP5661 also provides additional features such as

Enable and Error Flag (for the fixed output version), increasing the

utility of this device. A thermally robust, 5 pin DPAK, combined with

an architecture that offers low ground current (independent of load),

provides for a superior high−current LDO solution.

APPLICATION INFORMATION

Adjustable Output Operation

The NCP5661 is a high performance low dropout 1.0 A

linear regulator suitable for high power applications,

featuring an ultra−fast response time and low noise without

a bypass capacitor. It is offered in both fixed and adjustable

output versions with voltages as low as 0.9 V. Additional

features, such as Enable and Error Flag (fixed output

version) increase the utility of the NCP5661. It is thermally

robust and includes the safety features necessary during a

fault condition, which provide for an attractive high current

LDO solution for server, ASIC power supplies, networking

equipment applications, and many others.

The application circuit for the adjustable output version is

shown in Figure 1. The reference voltage is 0.9 V and the

adjustable pin current is typically 40 nA. A resistor divider

network, R1 and R2, is calculated using the following

formula:

out

ref

_{R1 + R2}ǒ _{* 1}Ǔ

Current Limit Operation

As the peak output current increases beyond its limitation,

the device is internally clampled to 1.5 A, thus causing the

output voltage to decrease and go out of regulation. This

allows the device never to exceed the maximum power

dissipation.

Input Capacitor

The recommended input capacitor value is a 150 mF

OSCON with an Equivalent Series Resistance (ESR) of

50 mW. It is especially required if the power source is

located more than a few inches from the NCP5661. 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 Vin

and GND traces should be sufficiently wide to minimize

noise and unstable operation.

Error Flag Operation

The Error Flag pin on the NCP5661 will produce a logic

Low when it drops below the nominal output voltage. Refer

to the electrical characteristics for the threshold values at

which point the Error Flag goes Low. When the NCP5661

is above the nominal output voltage, the Error Flag will

remain at logic High.

The external pullup resistor needs to be connected

Output Capacitor

between V (Pin 1) and the Error Flag pin (Pin 5). A resistor

Proper output capacitor selection is required to maintain

stability. The NCP5661 is guaranteed to be stable at an

of approximately 100 kW is recommended to minimize the

current consumption. No pullup resistor is required if the

Error Flag output is not being used.

output capacitance of, C > 10 mF with an ESR < 300 mW

out

over the output current range of 10 mA to 1.0 A. For PCB

layout considerations, place the recommended ceramic

capacitor close to the output pin and keep the leads short.

This should help ensure ultra−fast transient response times.
