| NCP4587 Product Preview 150 mA, Tri-Mode, LDO Linear Voltage Regulator The NCP4587 is a CMOS 150 mA LDO which switches to a low power mode under light current loads. The device automatically switches back to a fast response mode as the output load increases above 3 mA (typ.) or it can be placed in permanent fast mode through a mode select pin. The family is available in a variety of packages: SC-70, SOT23 and an ultra thin (0.4 mm) small 1.2 x 1.2 mm XDFN.

VIN C1 1m NCP4587x VIN CE AE GND VOUT C2 1m VOUT is above logic high level. Enable pin has internal pull down current source. If enable function is not needed connect CE pin to VIN. Output Discharger The D version includes a transistor between VOUT and GND that is used for faster discharging of the output capacitor. This function is activated when the IC goes into disable mode. Auto ECO and Fast Mode Figure 3. Typical Application Schematic Input Decoupling Capacitor (C1) The NCP4587 has two operation modes that have impact on supply current and transient response at low output current. These two modes can be selected by AE pin. If AE pin is at low level Auto ECO mode is available. Please, see supply current vs. output current charts. Thermal A 1 mF ceramic input decoupling capacitor should be connected as close as possible to the input and ground pin of the NCP4587. Higher values and lower ESR improves line transient response. Output Decoupling Capacitor (C2) A 1 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. If output capacitor is composed from few ceramic capacitors in parallel, the operation can be unstable. 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 As power across the IC increases, 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 rise for the part. That is to say, when the device has good thermal conductivity through the PCB, the junction temperature will be relatively low with high power dissipation applications. PCB layout Make VIN and GND line 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. Enable pin CE may be used for turning the regulator on and off. The regulator is switched on when CE pin voltage ORDERING INFORMATION Device NCP4587DMU12TCG NCP4587DMU18TCG NCP4587DMU28TCG NCP4587DMU30TCG NCP4587DMU33TCG Nominal Output Voltage 1.2 V 1.8 V 2.8 V 3.0 V 3.3 V Description Auto discharge Auto discharge Auto discharge Auto discharge Auto discharge Marking Package XDFN (Pb-Free) XDFN (Pb-Free) XDFN (Pb-Free) XDFN (Pb-Free) XDFN (Pb-Free) Shipping 5000 / Tape & Reel 5000 / Tape & Reel 5000 / Tape & Reel 5000 / Tape & Reel 5000 / Tape & Reel YE YL YW YY ZB For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.
