NV8664ST50T3GEVB NCV8664 Evaluation Board User's Manual http://onsemi.com EVAL BOARD USER’S MANUAL Description • Wide Input Voltage Operating Range of 5.5 V to 45 V • Internal Fault Protection • −42 V Reverse Voltage • Short Circuit/Overcurrent • Thermal Overload The NCV8664 is a precision 3.3 V and 5.0 V fixed output, low dropout integrated voltage regulator with an output current capability of 150 mA. Careful management of light load current consumption, combined with a low leakage process, achieve a typical quiescent ground current of 22 mA. The output voltage is accurate within ±2.0%, and maximum dropout voltage is 600 mV at full rated load current. The following ceramic capacitors are the recommended values to be used with these devices; Cin = 0.1 mF, Cout = 10 mF. Board Notes Max voltage on Vin cap not to exceed 35 V. Board Layouts These boards are shown in sets of 2 due to the minimum board size requirement of most board fabrication houses. When sent out for fabrication, it must be indicated that the center line of the board set be V−scored to allow board separation. Features • ±2.0% Output Accuracy, Over Full Temperature Range • 30 mA Maximum Quiescent Current at Iout = 100 mA • 600 mV Maximum Dropout Voltage at 150 mA Load Current Figure 1.
