NCP5500, NCV5500, NCP5501, NCV5501 500 mA Linear Regulator
These linear regulators provide up to 500 mA over a user-adjustable output range of 1.25 V to 5.0 V, or at a fixed output voltage of 1.5 V or 5.0 V*, with typical output voltage accuracy better than 3%. NCV versions are qualified for demanding automotive applications that require site and change control. NCP5500 and NCV5500 versions include an Enable/Shutdown function and are available in a DPAK-5L power package. In shutdown, current consumption is reduced to 30 mA. An internal PNP pass transistor permits low dropout voltage and operation at full load current at the minimum input voltage. NCP5501 and NCV5501 versions are available in DPAK-3L for applications that do not require logical on/off control. This regulator family is ideal for applications that require a broad input voltage range, including both automotive and portable battery powered devices. Integral protection features include short circuit current and thermal shutdown.

Figure 3. Measuring Circuits Circuit Description
The NCP5500/NCP5501/NCV5500/NCV5501 are integrated linear regulators with a DC load current capability of 500 mA. The output voltage is regulated by a PNP pass transistor controlled by an error amplifier and band gap reference. The choice of a PNP pass element provides the lowest possible dropout voltage, particularly at reduced load currents. Pass transistor base drive current is controlled to prevent oversaturation. The regulator is internally protected by both current limit and thermal shutdown. Thermal shutdown occurs when the junction temperature exceeds 150C. The NCV5500 includes an enable/shutdown pin to turn off the regulator to a low current drain standby state.
Regulator
electrolytic capacitor is best, since a film or ceramic capacitor with its almost zero ESR, can cause instability. The aluminum electrolytic capacitor is the least expensive solution. However, if the circuit operates at low temperatures (-25C to -40C), both capacitor value and ESR will vary considerably. The capacitor manufacturer's data sheet usually provides temperature performance data. Stability is guaranteed for COUT = 4.7 mF and ESR < 3 W.
Enable Input (NCP5500, NCV5500)
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 via a buffer. The reference is a bandgap design for enhanced temperature stability. Saturation control of the PNP pass transistor is a function of the load current and input voltage. Oversaturation of the output power device is prevented, and quiescent current in the ground pin is minimized.
Regulator Stability Considerations
The enable pin is used to turn the regulator on or off. By holding the pin at a voltage less than 0.5 V, the output of the regulator will be turned off to a minimal current drain state. When the voltage at the Enable pin is greater than 2.0 V, the output of the regulator will be enabled and rise to the regulated output voltage. The Enable pin may be connected directly to the input pin to provide a constant enable to the regulator.
Active Load Protection in Shutdown
(NCP5500, NCV5500)
The input capacitors (CBULK and CIN) are necessary to stabilize the input impedance to reduce transient line influences. The output 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
When a linear regulator is disabled (shutdown), the output (load) voltage should be zero. However, stray PC board leakage paths, output capacitor dielectric absorption, and inductively coupled power sources can cause an undesirable regulator output voltage if load current is low or zero. The NCV5500 features a load protection network that is active only during Shutdown mode. This network switches in a shunt current path (~500 mA) from VOUT to Ground. This feature also provides a controlled ("soft") discharge path for the output capacitor after a transition from Enable to Shutdown.

DEFINITION OF TERMS
Dropout Voltage: The input-to-output voltage differential at which the circuit ceases to regulate against further reduction input voltage. Measured when the output voltage has dropped 2% relative to the value measured at 6.0 V input, dropout voltage is dependent upon load current and junction temperature. Input Voltage: The DC voltage applied to the input terminals with respect to ground. Line Regulation: The change in output voltage for a change in the input voltage. The measurement is made under conditions of low dissipation or by using pulse techniques such that the average chip temperature is not significantly affected. Load Regulation: The change in output voltage for a change in load current at constant chip temperature. Pulse loading techniques are employed such that the average chip temperature is not significantly affected. Quiescent Current: The part of the positive input current that does not contribute to the positive load current. The regulator ground pin current with no load. Ripple Rejection: The ratio of the peak-to-peak input ripple voltage to the peak-to-peak output ripple voltage. Current Limit: Peak current that can be delivered to the output.
Calculating Power Dissipation
Once the value of PD(max) is known, the maximum permissible value of RqJA can be calculated:
R qJA + 150C * T A 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 less than the calculated value in Equation 2 will keep the die temperature below 150C. 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.
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:
R qJA + R qJC ) R qCS ) R qSA
(eq. 3)
The maximum power dissipation for a single output regulator (Figure 3) is:
P D(max) + V IN(max) * V OUT(min) I OUT(max) ) V IN(max)I q (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, IGND is the ground current at IOUT(max).
where RqJC is the junction-to-case thermal resistance, RqCS is the case-to-heatsink thermal resistance, RqSA is the heatsink-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, heat sink and the interface between them. These values appear in data sheets of heat sink manufacturers. Thermal, mounting, and heat sink considerations are further discussed in ON Semiconductor Application Note AN1040/D.
