NCV8184 Tracking Regulator/Line Driver - Micropower, Low Dropout 70 mA http://onsemi.com The NCV8184 is a monolithic integrated low dropout tracking voltage regulator designed to provide an adjustable buffered output voltage that closely tracks (±3.0 mV) the reference input. The part can be used in automotive applications with remote sensors, or any situation where it is necessary to isolate the output of your regulator. The NCV8184 also enables the user to bestow a quick upgrade to their module when added current is needed, and the existing regulator cannot provide. The versatility of this part also enables it to be used as a high−side driver. 1 SOIC−8 EP PD SUFFIX 8 CASE 751AC • 70 mA Source Capability • Output Tracks within ±3.0 mV • Low Input Voltage Tracking Performance PIN CONNECTIONS AND MARKING DIAGRAMS (Works Down to VREF = 2.1 V) Low Dropout (0.35 V Typ. @ 50 mA) Low Quiescent Current Thermal Shutdown Wide Operating Range Internally Fused Leads in SOIC−8 Package NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These Devices are Pb−Free and are RoHS Compliant VOUT Current Limit & Saturation Sense Adj − VREF/ENABLE + 1 VIN GND GND GND GND VREF/ENABLE Adj VOUT NC GND Adj 1 8 8184 AYWWG G VIN VOUT 8184 ALYW G • 1 DPAK 5−LEAD DT SUFFIX CASE 175AA 1 Features • • • • • • SOIC−8 D SUFFIX CASE 751 8184G ALYWW Pin Tab, VIN NC NC VREF/ENABLE 1.

When the VREF/ENABLE lead is greater than 2.1 V, VOUT tracks the VREF/ENABLE lead normally. The output is capable of supplying 70 mA to the load while configured as a similar (Figure 13), lower (Figure 15), or higher (Figure 14) voltage as the reference lead. The Adj lead acts as the inverting terminal of the op amp and the VREF lead as the non−inverting. The device can also be configured as a high−side driver as displayed in Figure 18.

In case of power supply generates voltage ripple (e.g. DC-DC converter) a passive low pass filter with C1 value at least 1 mF is required to suppress the ripple. The filter should be designed according to particular operating conditions and verified in the application. ** C2 is required for stability. *** C3 is recommended for EMC susceptibility http://onsemi.com 5 NCV8184 APPLICATION NOTES VOUT Short to Battery Figure 20. In this case the NCV8184 supply input voltage is set at 7.0 V when a short to battery (14 V typical) occurs on VOUT which normally runs at 5.0 V. The current into the device (ammeter in Figure 20) will draw additional current as displayed in Figure 21. The NCV8184 will survive a short to battery when hooked up the conventional way as shown in Figure 19. No damage to the part will occur.

Those packages with RqJA’s less than the calculated value in equation 2 will keep the die temperature below 150°C. In some cases, none of the packages will be sufficient to dissipate the heat generated by the IC, and an external heat sink will be required. The output capacitor for the NCV8184 is required for stability. Without it, the regulator output will oscillate. Actual size and type may vary depending upon the application load and temperature range. Capacitor effective series resistance (ESR) is also a factor in the IC stability. Worst−case is determined at the minimum ambient temperature and maximum load expected. The output capacitor can be increased in size to any desired value above the minimum. One possible purpose of this would be to maintain the output voltage during brief conditions of negative input transients that might be characteristic of a particular system. The capacitor must also be rated at all ambient temperatures expected in the system. To maintain regulator stability down to −40°C, a capacitor rated at that temperature must be used. More information on capacitor selection for SMART REGULATOR®s is available in the SMART REGULATOR application note, “Compensation for Linear Regulators,” document number SR003AN/D, available through our website at http://www.onsemi.com. VIN IOUT VOUT IQ Figure 23. Single Output Regulator with Key Performance Parameters Labeled Heatsinks A heatsink effectively increases the surface area of the package to improve the flow of heat away from the IC and into the surrounding air. Each material in the heat flow path between the IC and the outside environment will have a thermal resistance. Like series electrical resistances, these resistances are summed to determine the value of RqJA: The maximum power dissipation for a single output regulator (Figure 23) is: PD(max) + {VIN(max) * VOUT(min)} IOUT(max) (eq. 1) where: VIN(max) is the maximum input voltage, VOUT(min) is the minimum output voltage, IOUT(max) is the maximum output current, for the application,and IQ is the quiescent current the regulator consumes at IOUT(max). Once the value of PD(max) is known, the maximum permissible value of RqJA can be calculated: RqJA + 150° C * TA PD SMART REGULATOR® Control Features Calculating Power Dissipation in a Single Output Linear Regulator ) VIN(max)IQ IIN RqJA + RqJC ) RqCS ) RqSA (eq. 3) where: RqJC = the junction−to−case thermal resistance, RqCS = the case−to−heatsink thermal resistance, and RqSA = the heatsink−to−ambient thermal resistance. RqJC appears in the package section of the data sheet. Like RqJA, it is a function of package type. RqCS and RqSA are functions of the package type, heatsink and the interface between them. These values appear in heat sink data sheets of heatsink manufacturers.

Cauer networks can be easily implemented using circuit simulating tools, whereas Foster networks may be more easily implemented using mathematical tools (for instance, in a spreadsheet program), according to the following formula: R(t) + http://onsemi.com 12 n Ri ǒ1−e−tńtaui Ǔ S i+1 NCV8184 150 140 qJA (°C/W) 130 TJ = 25°C 120 110 1.0 oz Cu 100 90 2.0 oz Cu 80 70 60 0 100 200 300 400 500 600 700 COPPER HEAT SPREADER AREA (mm2) Figure 29.
