NCP4589 300 mA, Tri-Mode, LDO Linear Voltage Regulator The NCP4589 is a CMOS 300 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.). The device 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 a small, ultra thin 1.2 x 1.2 x 0.4 mm XDFN. http://onsemi.com MARKING DIAGRAMS Features • Operating Input Voltage Range: 1.4 V to 5.25 V • Output Voltage Range: 0.8 to 4.0 V (available in 0.1 V steps) • Supply Current: Low Power Mode – 1.0 mA at VOUT < 1.85 V • • • • • • • • Fast Mode – 55 mA Standby Mode – 0.1 mA Dropout Voltage: 230 mV Typ. at IOUT = 300 mA, VOUT = 2.8 V ±1% Output Voltage Accuracy (VOUT > 2 V, TJ = 25 °C) High PSRR: 70 dB at 1 kHz (Fast response mode) Line Regulation 0.02%/V Typ.

A typical application circuit for NCP4589 series is shown in Figure 87. NCP4589 VIN VIN C1 1m Current Limit This regulator includes fold-back type current limit circuit. This type of protection doesn’t limit current up to current capability in normal operation, but when over current occurs, the output voltage and current decrease until the over current condition ends. Typical characteristics of this protection type can be observed in the Output Voltage versus Output Current graphs shown in the typical characteristics chapter of this datasheet. C2 1m CE AE VOUT VOUT GND Figure 87. Typical Application Schematic 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. Input Decoupling Capacitor (C1) A 1 mF ceramic input decoupling capacitor should be connected as close as possible to the input and ground pin of the NCP4589. Higher values and lower ESR improves line transient response. Auto ECO and Fast Mode The NCP4589 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. 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. Thermal 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 Enable Operation The enable pin CE may be used for turning the regulator on and off. The regulator is switched on when CE pin voltage is above logic high level. The enable pin has internal pull http://onsemi.com 26 NCP4589 conductivity through the PCB, the junction temperature will be relatively low with high power dissipation applications. capacitors C1 and C2 as close as possible to the IC, and make wiring as short as possible. PCB layout Make VIN and GND line sufficient. If their impedance is high, noise pickup or unstable operation may result.
