NCV4279 5.0 V Micropower 150 mA LDO Linear Regulator with DELAY, Adjustable RESET, and Sense Output The NCV4279 is a 5.0 V precision micropower voltage regulator with an output current capability of 150 mA. The output voltage is accurate within ±2.0% with a maximum dropout voltage of 0.5 V at 100 mA. Low quiescent current is a feature drawing only 150 mA with a 1.0 mA load. This part is ideal for any and all battery operated microprocessor equipment. Microprocessor control logic includes an active reset output RO with delay and a SI/SO monitor which can be used to provide an early warning signal to the microprocessor of a potential impending reset signal. The use of the SI/SO monitor allows the microprocessor to finish any signal processing before the reset shuts the microprocessor down. The active Reset circuit operates correctly at an output voltage as low as 1.0 V. The Reset function is activated during the power up sequence or during normal operation if the output voltage drops outside the regulation limits. The reset threshold voltage can be decreased by the connection of an external resistor divider to the RADJ lead. The regulator is protected against reverse battery, short circuit, and thermal overload conditions. The device can withstand load dump transients making it suitable for use in automotive environments. The device has also been optimized for EMC conditions. If the application requires pullup resistors at the logic outputs Reset and Sense Out, the NCV4269 with integrated resistors can be used. http://onsemi.com MARKING DIAGRAMS 8 8 1 SO−8 D1 SUFFIX CASE 751 1 4279 ALYW G 14 14 1 SO−14 D2 SUFFIX CASE 751A NCV4279 AWLYWWG 1 A WL, L YY, Y WW, W G, G = Assembly Location = Wafer Lot = Year = Work Week = Lead Free Indicators ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 13 of this data sheet.

The output is controlled by a precision trimmed reference. The PNP output has drive quiescent current control for regulation while the input voltage is low, preventing over saturation. Current limit and voltage monitors complement the regulator design to give safe operating signals to the processor and control circuits. RESET DELAY (D) The reset delay circuit provides a delay (programmable by capacitor CD) on the reset output lead RO. The delay lead D provides charge current ID,C (typically 6.5 mA) to the external delay capacitor CD during the following times: 1. During Powerup (once the regulation threshold has been exceeded). 2. After a reset event has occurred and the device is back in regulation. The delay capacitor is set to discharge when the regulation (VRT, reset threshold voltage) has been violated. When the delay capacitor discharges to VLD, the reset signal RO pulls low. RESET OUTPUT (RO) A reset signal, Reset Output, RO, (low voltage) is generated as the IC powers up. After the output voltage VQ increases above the reset threshold voltage VRT, the delay timer D is started. When the voltage on the delay timer VD passes VUD, the reset signal RO goes high. A discharge of the delay timer VD is started when VQ drops and stays below the reset threshold voltage VRT. When the voltage of the delay timer VD drops below the lower threshold voltage VLD the reset output voltage VRO is brought low to reset the processor. The reset output RO is an open collector NPN transistor, controlled by a low voltage detection circuit. The circuit is functionally independent of the rest of the IC, thereby guaranteeing that RO is valid for VQ as low as 1.0 V. SETTING THE DELAY TIME The delay time is set by the delay capacitor CD and the charge current ID. The time is measured by the delay capacitor voltage charging from the low level of VDSAT to the higher level VUD. The time delay follows the equation: td + [CD (VUD * VD, SAT)]ńID RESET ADJUST (RADJ) Example: Using CD = 100 nF. Use the typical value for VD,SAT = 0.1 V. Use the typical value for VUD = 1.8 V. Use the typical value for Delay Charge Current ID = 6.5 mA. The reset threshold VRT can be decreased from a typical value of 4.65 V to as low as 3.5 V by using an external voltage divider connected from the Q lead to the pin RADJ, as shown in Figure 20. The resistor divider keeps the voltage above the VRADJ,TH (typical 1.35 V) for the desired input voltages, and overrides the internal threshold detector. Adjust the voltage divider according to the following relationship: I CI* Q VDD CQ** 10 mF RADJ1 0.1 mF RADJ RADJ2 NCV4279 D RSI1 RRO SI RSI2 CD SO Microprocessor VBAT td + [100 nF (1.8 * 0.1 V)] ń 6.5 mA + 26.2 ms (eq. 1) VRT + VRADJ, TH @ (RADJ1 ) RADJ2) ń RADJ2 (eq. 2) RSO RO I/O GND *CI required if regulator is located far from the power supply filter. ** CQ required for Stability. Cap must operate at minimum temperature expected. Figure 20. Application Diagram http://onsemi.com 11 I/O (eq. 3) NCV4279 SENSE INPUT (SI) / SENSE OUTPUT (SO) VOLTAGE MONITOR 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 CQ shown in Figure 20 should work for most applications; however, it is not necessarily the optimized solution. Stability is guaranteed at values CQ = 10 mF and an ESR = 10 W within the operating temperature range. Actual limits are shown in a graph in the typical data section. An on−chip comparator is available to provide early warning to the microprocessor of a possible reset signal. The output is from an open collector driver. The reset signal typically turns the microprocessor off instantaneously. This can cause unpredictable results with the microprocessor. The signal received from the SO pin will allow the microprocessor time to complete its present task before shutting down. This function is performed by a comparator referenced to the band gap voltage. The actual trip point can be programmed externally using a resistor divider to the input monitor SI (Figure 20). The values for RSI1 and RSI2 are selected for a typical threshold of 1.20 V on the SI Pin. CALCULATING POWER DISSIPATION IN A SINGLE OUTPUT LINEAR REGULATOR The maximum power dissipation for a single output regulator (Figure 20) is: SIGNAL OUTPUT PD(max) + [VI(max) * VQ(min)] IQ(max) ) VI(max) Iq (eq. 4) Figure 21 shows the SO Monitor timing waveforms as a result of the circuit depicted in Figure 20. As the output voltage (VQ) falls, the monitor threshold (VSILOW), is crossed. This causes the voltage on the SO output to go low sending a warning signal to the microprocessor that a reset signal may occur in a short period of time. TWARNING is the time the microprocessor has to complete the function it is currently working on and get ready for the reset shutdown signal. where: VI(max) is the maximum input voltage, VQ(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: RqJA = (150°C – TA) / PD VQ (eq. 5) 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 heatsink will be required. The current flow and voltages are shown in the Measurement Circuit Diagram. SI VSI,Low VRO 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: SO TWARNING Figure 21. SO Warning Waveform Time Diagram RqJA + RqJC ) RqCS ) RqSA STABILITY CONSIDERATIONS (eq. 6) 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. RqJC 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, heatsink and the interface between them. These values appear in data sheets of heatsink manufacturers. Thermal, mounting, and heatsinking considerations are discussed in the ON Semiconductor application note AN1040/D, available on the ON Semiconductor website. The input capacitor CI in Figure 20 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 1.0 W in series with CI. The output or compensation capacitor 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. A tantalum or aluminum electrolytic capacitor is best, since a film or ceramic capacitor with almost zero ESR can cause instability. The aluminum electrolytic capacitor is the least http://onsemi.com 12 NCV4279 ORDERING INFORMATION Package Shipping† NCV4279D1G SO−8 (Pb−Free) 98 Units/Rail NCV4279D1R2G SO−8 (Pb−Free) 2500 Tape & Reel SO−14 (Pb−Free) 55 Units/Rail SO−14 (Pb−Free) 2500 Tape & Reel Device NCV4279D2G Output Voltage 5.0 V NCV4279D2R2G †For information on tape and reel specifications,including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D. http://onsemi.com 13 NCV4279 PACKAGE DIMENSIONS SO−8 CASE 751−07 ISSUE AJ −X− NOTES: 1.
