Characteristic Symbol Min Typ Max Unit NCP630G Output Voltage (Vin = 5.0 V to 7.0 V, Iout = 10 mA to 3.0 A, TJ = 25°C) (Vin = 5.0 V to 7.0 V, Iout = 10 mA to 3.0 A, TJ = 0°C to 125°C) Vout 3.418 3.383 3.470 - 3.522 3.557 V Line Regulation (Notes 6 and 7) (Vin = 5.0 V to 7.0 V, TJ = 25°C) (Vin = 5.0 V to 7.0 V, TJ = 0°C to 125°C) Regline - - 0.02 0.06 - - % Load Regulation (Notes 6 and 7) (Iout = 10 mA to 3.0 A, TJ = 25°C) (Iout = 10 mA to 3.0 A, TJ = 0°C to 125°C) Regload - - 0.01 0.06 - - % Dropout Voltage (Measured at Vout – 2%) (Iout = 300 mA) (Iout = 3.0 A) Vin-V out - - 0.75 1.0 1.0 1.25 V Ground Pin Current in Normal Mode (Iout = 300 mA) (Iout = 3.0 A) IGnd - - 0.4 1.0 1.0 2.0 mA Ground Pin Current in Shutdown Mode (Vshutdown = 0.8 V) IGnd - 26 50 mA Peak Output Limit Iout 3.0 5.0 - A Short Current Limit (Note 8) ISC - 5.0 - A Thermal Shutdown - - 165 - °C Shutdown Input Threshold Voltage (Voltage Increasing, Output Turns On, Logic High) (Voltage Decreasing, Output Turns Off, Logic Low) Vtth(shutdown) 2.0 - - - - 0.8 V Turn-of f Delay, Iout = 3.0 A TD(off) - 20 - ms Turn-on Delay, Iout = 3.0 A TD(on) - 25 - ms Shutdown Input Low Current (Vin = 0.8 V), (Negative current flows out of pin) IIL -10 -5.0 -1.0 mA Shutdown Input High Current (Vin = 2.0 V), (Negative current flows out of pin) IIH -10 -4.5 -1.0 mA Ripple Rejection (Cout = 100 mF, f = 1.0 kHz) RR - 85 - dB Output Noise Density (f = 120 Hz) - - 0.6 - mV Hz Output Noise Voltage (f = 10 Hz – 100 kHz) Vn - 210 - mVrms 6. Low duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible. 7. Line regulation is defined as the change in output voltage for a change in input voltage. Load regulation is defined as the change in output voltage for a change in output load current at a constant temperature. The limits for line and load regulation are contained within the output voltage specification, Vout. Typical numbers are included in the specification for line and load regulation. 8. The short circuit limit is for device protection. Maximum output current is guaranteed to be greater or equal to 3.0 A with a 5.0 A typical as listed in the peak output limit specification. |
