NCP59300

NCP59300 3.0A, Very Low-Dropout (VLDO) Fast Transient Response Regulator series The NCP59300 series are high precision, very low dropout (VLDO), low ground current positive voltage regulators that are capable of providing an output current in excess of 3.0 A with a typical dropout voltage lower than 300 mV at 3.0 A load current. The devices are stable with ceramic output capacitors. This series consists initially of an Adjustable output voltage version, with fixed voltage versions planned in the future. The NCP59300 series can withstand up to 18 V max input voltage. Internal protection features consist of output current limiting, built−in thermal shutdown and reverse output current protection. Logic level enable and error flag pins are available on the 5−pin version. The NCP59302 is an Adjustable voltage Device and is available in D2PAK−5 package.

The NCP59300 series is designed to operate with ceramic output capacitors. The recommended output capacitance value is 47 mF or greater. Such capacitors help to improve transient response and noise reduction at high frequency. Input Capacitor An input capacitor of 1.0 mF or greater is recommended when the device is more than 4 inches away from the bulk supply capacitance, or when the supply is a battery. Small, surface−mount chip capacitors can be used for the bypassing. The capacitor should be place within 1 inch of the device for optimal performance. Larger values will help to improve ripple rejection by bypassing the input of the regulator, further improving the integrity of the output voltage. Minimum Load Current Thermal shutdown disables the NCP59300 device when the die temperature exceeds the maximum safe operating temperature. When (VOUT – VIN) voltage difference is less than 6.5 V in the application, the output structure of these regulators is able to withstand output voltage (backup battery as example) to be applied without reverse current flow. Of course the additional current flowing through the internal Feedback resistor divider at the NCP59300 Fix voltage versions needs to be included in the backup battery discharging calculations. Adjustable Voltage Design The NCP59300 regulator is specified between finite loads. A 10 mA minimum load current is necessary for proper operation. Error Flag The NCP/NCV59302 Adjustable voltage Device Output voltage is set by the ratio of two external resistors as shown in Figure 23. The device maintains the voltage at the ADJ pin at 1.24 V referenced to ground. The current in R2 is then equal to 1.24 V / R2, and the current in R1 is the current in R2 plus the ADJ pin bias current. The ADJ pin bias current flows from VOUT through R1 into the ADJ pin. The output voltage can be calculated using the formula shown in Figure 23. VIN + CIN EN GND R2 ADJ NCP59302 VIN VOUT R1 + COUT 47 mF, Ceramic VOUT Some NCP59300 series members feature an error flag circuit that monitors the output voltage and signals an error condition when the voltage is 5% below the nominal output voltage. The error flag is an open−collector output that can sink up to 5 mA typically during a VOUT fault condition. The FLG output is overload protected when a short circuit of the pullup load resistor occurs in the application. This is guaranteed in the full range of FLG output voltage Max ratings (see Max Ratings table). Enable Input Some NCP59300 series members also feature an enable input for on/off control of the device. It’s shutdown state draws “zero” current from input voltage supply (only microamperes of leakage). The enable input is TTL/CMOS compatible for simple logic interface, but can be connected up to VIN. Overcurrent and Reverse Output Current Protection R1 ) I ADJ @ R1 R2 Figure 23. Adjustable Voltage Operation V OUT + 1.24 V @ 1 ) Thermal Considerations The NCP59300 regulator is fully protected from damage due to output current overload conditions. When NCP59300 output is overloaded, Output Current limiting is provided. This limiting is linear; output current during overload conditions is constant. The device is also capable to withstand power−on or enable start−up with output shorted to ground for the full Recommended Operating Conditions range. These features are advantageous for powering FPGAs and other ICs having current consumption higher than nominal during their startup. The power handling capability of the device is limited by the maximum rated junction temperature (125°C). The PD total power dissipated by the device has two components, Input to output voltage differential multiplied by Output current and Input voltage multiplied by GND pin current. P D + V IN * V OUT @ I OUT ) V IN @ I GND (eq. 1) The GND pin current value can be found in Electrical Characteristics table and in Typical Characteristics graphs. The Junction temperature TJ is T J + T A ) P D @ R qJA (eq. 2) where TA is ambient temperature and RqJA is the Junction to Ambient Thermal Resistance of the NCP/NCV59300 device mounted on the specific PCB. http://onsemi.com 9 NCP59300 To maximize efficiency of the application and minimize thermal power dissipation of the device it is convenient to use the Input to output voltage differential as low as possible.
