NCP583 Ultra−Low Iq 150 mA CMOS LDO Regulator with Enable The NCP583 series of low dropout regulators are designed for portable battery powered applications which require precise output voltage accuracy and low quiescent current. These devices feature an enable function which lowers current consumption significantly and are offered in two small packages; SC−82AB and the SOT−563. A 1.0 mF ceramic capacitor is the recommended value to be used with these devices on the output pin. http://onsemi.com MARKING DIAGRAMS Features • • • Ultra−Low Dropout Voltage of 250 mV at 150 mA Excellent Line Regulation of 0.05%/V Excellent Load Regulation of 20 mV High Output Voltage Accuracy of "2% Ultra−Low Iq Current of 1.0 mA Very Low Shutdown Current of 0.1 mA Wide Output Voltage Range of 1.5 V to 3.3 V Low Temperature Drift Coefficient on the Output Voltage of "100 ppm/°C Fold Back Protection Circuit Input Voltage up to 6.5 V These are Pb−Free Devices Typical Applications • Portable Equipment • Hand−Held Instrumentation • Camcorders and Cameras SC−82AB SQ SUFFIX CASE 419C 4 M • • • • • • • • 1 1 SOT−563 XV SUFFIX CASE 463A 6 xxx M G G xxx M G G 1 1 xxx = Device Code M = Date Code* G = Pb−Free Package (Note: Microdot may be in either location) *Date Code orientation and/or position may vary depending upon manufacturing location.

For PCB layout considerations, the traces of Vin and GND should be sufficiently wide in order to minimize noise and prevent unstable operation. It is recommended to use a 0.1 mF ceramic capacitor on the Vout pin. For better performance, select a capacitor with low Equivalent Series Resistance (ESR). For PCB layout considerations, place the output capacitor close to the output pin and keep the leads short as possible.
