NCV8503 Series Micropower 400 mA LDO Linear Regulators with ENABLE, DELAY, Adjustable RESET, and General Use Comparator http://onsemi.com The NCV8503 is a family of precision micropower voltage regulators. Their output current capability is 400 mA. The family has output voltage options for Adjustable, 2.5 V, 3.3 V and 5.0 V. The output voltage is accurate within ± 2.0% with a maximum dropout voltage of 0.6 V at 400 mA. Low quiescent current is a feature drawing less than 1.0 µA with ENABLE = 0 V. With ENABLE = 5.0 V, the part only draws 200 µA with 100 µA load. This part is ideal for any and all battery operated microprocessor equipment. Microprocessor control logic includes an active RESET (with DELAY). 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 below the regulation limits. The reset threshold voltage can be decreased by the connection of external resistor divider to RADJ lead. The general use comparator (FLAG/Monitor) is referenced to a temperature stable voltage and provides 1.0 mA of drive current at its open collector output. 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. • • 16 16 1 SOIC 16 LEAD WIDE BODY EXPOSED PAD PDW SUFFIX CASE 751R NCV8503x AWLYYWW 1 x = Voltage Ratings as Indicated Below: A = Adjustable 2 = 2.5 V 3 = 3.3 V 5 = 5.0 V A = Assembly Location WL = Wafer Lot YY = Year WW = Work Week ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 12 of this data sheet.

The part stays in a low IQ sleep mode when the ENABLE pin is held low. The part has an internal pull down if the pin is left floating. The integrity of the ENABLE pin allows it to be tied to the battery line through an external resistor. It will withstand load dump potentials in this configuration. VIN RESET Threshold VOUT DELAY VBAT Up to 45 V NCV8503 DELAY Threshold (VDT) RESET Td VOUT VIN 10 k ENABLE GND Td Figure 13. Reset and Delay Circuit Wave Forms Figure 15. ENABLE Function RESET Function A RESET signal (low voltage) is generated as the IC powers up until VOUT is within 1.5% of the regulated output voltage, or when VOUT drops out of regulation,and is lower than 4.0% below the regulated output voltage. Hysteresis is included in the function to minimize oscillations. The RESET output 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 the RESET signal is valid for VOUT as low as 1.0 V. DELAY Function The reset delay circuit provides a programmable (by external capacitor) delay on the RESET output lead. The DELAY lead provides source current (typically 4.0 µA) to the external DELAY capacitor during the following proceedings: 1. During Power Up (once the regulation threshold has been verified). 2. After a reset event has occurred and the device is back in regulation. The DELAY capacitor is discharged when the regulation (RESET threshold) has been violated. This is a latched incident. The capacitor will fully discharge and wait for the device to regulate before going through the delay time event again. Adjustable Reset Function The reset threshold can be made lower by connecting an external resistor divider to the RADJ lead from the VOUT lead, as displayed in Figure 14. This lead is grounded to select the default value of 4.6 V (on the 5.0 V option). VR(ADJ) VOUT RADJ NCV8503 DELAY FLAG/Monitor Comparator to µP and System Power RRST RESET A general use comparator is included whose positive input terminal is tied to the on−chip band gap voltage reference. This provides a very temperature stable referenced comparator with versatile uses in any system. The trip point can be programmed externally using a resistor divider to the input monitor (MON) (Figure 16). The typical threshold is 1.28 V on the MON pin.

As the input voltage falls (VMON), the Monitor threshold is crossed. This causes the voltage on the FLAG output to go low. STABILITY CONSIDERATIONS The output or compensation capacitor helps determine three main characteristics of a linear regulator: start−up 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 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 manufacturers data sheet usually provides this information. The value for the output capacitor COUT shown in Figure 19 should work for most applications, however it is not necessarily the optimized solution. VMON MON Flag Monitor Ref.

Those packages with RJA’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. 90 80 70 60 VIN 50 40 IOUT IIN 0 200 400 600 Copper Area (mm2) IQ Figure 21. Single Output Regulator with Key Performance Parameters Labeled 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 RJA: CALCULATING POWER DISSIPATION IN A SINGLE OUTPUT LINEAR REGULATOR The maximum power dissipation for a single output regulator (Figure 21) is: (1) VIN(max)IQ 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 RJA can be calculated: T RJA 150°C A PD VOUT } Control Features 800 Figure 20. 16 Lead SOW (Exposed Pad), JA as a Function of the Pad Copper Area (2 oz.

RJC appears in the package section of the data sheet. Like RJA, it too is a function of package type. RCS and RSA are functions of the package type, heatsink and the interface between them. These values appear in heat sink data sheets of heat sink manufacturers.
