NCV8664 Ultra−Low Iq Low Dropout Linear Regulator 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 current of 22 mA. NCV8664 is pin and functionally compatible with NCV4264 and NCV4264−2, and it could replace these parts when very low quiescent current is required. The output voltage is accurate within "2.0%, and maximum dropout voltage is 600 mV at full rated load current. It is internally protected against input supply reversal, output overcurrent faults, and excess die temperature. No external components are required to enable these features. http://onsemi.com MARKING DIAGRAMS TAB 1 2 3 4 Features • • • • • • • • • • 3.3 V, 5.0 V Fixed Output "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 Wide Input Voltage Operating Range of 4.5 V to 45 V Internal Fault Protection ♦ −42 V Reverse Voltage ♦ Short Circuit/Overcurrent ♦ Thermal Overload NCV Prefix for Automotive and Other Applications Requiring Site and Control Changes AEC−Q100 Qualified EMC Compliant This is a Pb−Free Device 1 2 SOT−223 ST SUFFIX CASE 318E AYM V664x 1 DPAK DT SUFFIX CASE 369C 3 V66450G ALYWW 1 x A L Y WW M G = Voltage Rating (5 = 5.0 V Version) (3 = 3.3 V Version) = Assembly Location = Wafer Lot = Year = Work Week = Date Code = Pb−Free Package PIN CONNECTIONS PIN 1 2, TAB 3 FUNCTION VIN GND VOUT ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 11 of this data sheet. © Semiconductor Components Industries, LLC, 2007 March, 2007 − Rev. 7 1 Publication Order Number: NCV8664/D NCV8664 IN OUT Bias Current Generators 1.3 V Reference + Error Amp − Thermal Shutdown GND Figure 1.

Careful management of light load consumption combined with a low leakage process results in a typical quiescent current of 22 mA. The device has current capability of 150 mA, with 600 mV of dropout voltage at full rated load current. The regulation is provided by a PNP pass transistor controlled by an error amplifier with a bandgap reference. The regulator is protected by both current limit and short circuit protection. Thermal shutdown occurs above 150°C to protect the IC during overloads and extreme ambient temperatures. The maximum power dissipation for a single output regulator (Figure 3) is: PD(max) + [VIN(max) * VOUT(min)] @ IQ(max) ) VI(max) @ Iq (eq. 1) Where: VIN(max) is the maximum input voltage, VOUT(min) is the minimum output voltage, IQ(max) is the maximum output current for the application, and Iq is the quiescent current the regulator consumes at IQ(max). Once the value of PD(Max) is known, the maximum permissible value of RqJA can be calculated: Regulator The error amplifier compares the reference voltage to a sample of the output voltage (Vout) and drives the base of a PNP series pass transistor by a buffer. The reference is a bandgap design to give it a temperature−stable output. Saturation control of the PNP is a function of the load current and input voltage. Over saturation of the output power device is prevented, and quiescent current in the ground pin is minimized. PqJA + 150 oC * TA PD (eq. 2) The value of RqJA can then be compared with those in the package section of the data sheet. 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 current flow and voltages are shown in the Measurement Circuit Diagram. Regulator Stability Considerations The input capacitor CIN in Figure 2 is necessary for compensating input line reactance. Possible oscillations caused by input inductance and input capacitance can be damped by using a resistor of approximately 1 W in series with CIN. The output or compensation capacitor, COUT helps determine three main characteristics of a linear regulator: startup delay, load transient response and loop stability. The capacitor value and type should be based on cost, availability, size and temperature constraints. Tantalum, aluminum electrolytic, film, or ceramic capacitors are all acceptable solutions, however, attention must be paid to ESR constraints. The aluminum electrolytic capacitor is the least expensive solution, but, if the circuit operates at low temperatures (−25°C to −40°C), both the value and ESR of the capacitor will vary considerably. The capacitor manufacturer’s data sheet usually provides this information. The value for the output capacitor COUT shown in Figure 2 should work for most applications; however, it is not necessarily the optimized solution. Stability is guaranteed at values COUT ≥ 10 mF for 5.0 V version, and COUT ≥ 22 mF for 3.3 V version and an ESR ≤ 9 W within the operating temperature range. Actual limits are shown in a graph in the Typical Performance Characteristics section. Heat Sinks A heat sink 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: RqJA + RqJC ) RqCS ) RqSA (eq. 3) Where: RqJC = the junction−to−case thermal resistance, RqCS = the case−to−heat sink thermal resistance, and RqSA = the heat sink−to−ambient thermal resistance. RqJA appears in the package section of the data sheet. Like RqJA, it too is a function of package type. RqCS and RqSA are functions of the package type, heat sink and the interface between them. These values appear in data sheets of heat sink manufacturers. Thermal, mounting, and heat sinking are discussed in the ON Semiconductor application note AN1040/D, available on the ON Semiconductor Website. http://onsemi.com 9 NCV8664 EMC−Characteristics: Conducted Susceptibility Direct Power Injection: 33 dBm forward power CW Acceptance Criteria: Amplitude Dev. max 2% of Output Voltage All EMC−Characteristics are based on limited samples and not part of production testing, according to 47A/658/CD IEC62132−4 (Direct Power Injection) Test Conditions Supply Voltage Temperature Load VIN = 12 V TA = 23°C ±5°C RL = 35 W U1 X1 VIN_HF 1 F3 FERRITE VIN VOUT GND C1 C2 + 10 mF X2 VIN_MON NCV8664 2 47 nF X3 VOUT_HF 3 C3 10 nF C4 10 mF + F1 FERRITE X4 VOUT_MON F2 FERRITE X5 GND_HF X6 GND_MON Figure 25.
