2 / 8 page  NCP5426 http://onsemi.com 2 DETAILED PIN DESCRIPTION Pin Name Description 1 Enable The enable pin allows the user to control the output. A low signal disables the output and places the device into a low current standby mode. 2 GND Ground pin. 3 N/C This pin is not connected to the device. 4 Vout Regulated output voltage. 5 Vin Input voltage. MAXIMUM RATINGS Rating Symbol Value Unit Max Voltage, All Pins VMAX 12 V Power Dissipation to Air PA 150 mW Power Dissipation, Board Mounted P 600 mW Operating and Storage Temperature TA −40 to 85 °C Thermal Resistance TJA 300 °C/W Junction Temperature TJ 125 °C Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. ELECTRICAL CHARACTERISTICS (TA = 25°C, for min/max values TA is the operating junction temperature that applies, VCC = 3.5 V, unless otherwise noted) Characteristic Symbol Min Typ Max Unit Operating Voltage VCC − − 12 V Operating Voltage Turn On, Iout = 30 mA, Increasing VCC VCCON − 2.6 2.8 V Operating Voltage Turn Off, Iout = 30 mA, Decreasing VCC VCCOFF 2.0 2.1 2.2 V Operating Voltage Hysteresis, Iout = 30 mA VCC(hyst) 400 500 600 mV Operating Current No Load ICC − 120 240 mA Operating Current, VCC = 1.8 V, Enable High ICC(uvlo) − 80 160 mA Operating Current, Enable Low ICC(off) − − 0.1 mA Maximum Output Current, Vout = 0.95 *Vnom Iout(max) 150 − − mA Overcurrent Protection, Vout = 0 V Iout(limit) − 270 − mA Load Regulation, Vin = 3.5 V, Iout 1.0 to 100 mA Regload − 30 60 mV Line Regulation, Iout = 30 mA, Vin 3.0 to 5.0 V Regline − 10 20 mV Ripple Rejection, Vin 3.5 V, f 120 Hz, Vpp 1.0 V, Iout 30 mA RR 55 70 − dB Temperature Shutdown Tstd − 150 − °C VCC Low Detector Temperature Coefficient, Iout = 30 mA, T = −40 to 85 °C DVCC H to L/DT − 200 − ppm/ °C Vout Temperature Coefficient DVo/DT − 100 − ppm/ °C Enable Pin High Threshold Veh 1.6 − − V Enable Pin Low Threshold Vel − − 0.4 V Enable Pin Current, Ve = 1.6 V le − 5.0 10 mA −1.3 V Output Voltage, Iout = 30 mA Vout 1.261 1.3 1.339 V |
