NCP4629 Product Preview 500 mA, Wide Input Range, LDO Linear Voltage Regulator
The NCP4629 is a CMOS 500 mA LDO linear voltage regulator which features a high input voltage range while maintaining a low quiescent current. Several protection features like current limiting and thermal shutdown are fully integrated to create a versatile and robust device. A high maximum input voltage (36 V) and wide temperature range (-40C to 105C) makes the NCP4629 an ideal choice for high power industrial applications.

APPLICATION INFORMATION A typical application circuit for NCP4629 series is shown in Figure 3.
VIN C1 470 n NCP4629x VIN CE GND VOUT C2 10 m VOUT
Output Decoupling Capacitor (C2)
A 10 mF ceramic output decoupling capacitor is sufficient to achieve stable operation of the IC. If tantalum capacitor is used, and its ESR is high, the loop oscillation may result. The capacitor should be connected as close as possible to the output and ground pin. Larger values and lower ESR improves dynamic parameters.
Enable Operation
Figure 3. Typical Application Schematic
The enable pin CE may be used for turning the regulator on and off. The IC is switched on when a high level voltage is applied to the CE pin. The enable pin has an internal pull down current source. If the enable function is not needed connect CE pin to VIN.
Thermal
When VOUT voltage could be higher than VIN voltage it is necessary to use protective diode D1. If there is possibility that VOUT voltage could be negative then it is necessary to use schottky diode D2. See Figure 4 for details. Do not force the voltage to the VOUT pin.

As a power across the IC increase, it might become necessary to provide some thermal relief. The maximum power dissipation supported by the device is dependent upon board design and layout. Mounting pad configuration on the PCB, the board material, and also the ambient temperature affect the rate of temperature increase for the part. When the device has good thermal conductivity through the PCB the junction temperature will be relatively low in high power dissipation applications. The IC includes internal thermal shutdown circuit that stops operation of regulator, if junction temperature is higher than 160C. After that, when junction temperature decreases below 135C, the operation of voltage regulator would restart. While high power dissipation condition is, the regulator starts and stops repeatedly and protects itself against overheating.
PCB layout
Figure 4. Typical Application Schematic with Protective Diodes Input Decoupling Capacitor (C1)
A 470 nF ceramic input decoupling capacitor should be connected as close as possible to the input and ground pin of the NCP4629. Higher values and lower ESR improves line transient response.

Pins number 2 and 3 must be wired to the GND plane while it is mounted on board. Make VIN and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect capacitors C1 and C2 as close as possible to the IC, and make wiring as short as possible.
