Simplified Schematic Block Diagram PIN FUNCTION DESCRIPTION Pin No. XDFN6 Pin Name 1 OUT1 Regulated output voltage of the first channel. A small 0.22 mF ceramic capacitor is needed from this pin to ground to assure stability. 2 OUT2 Regulated output voltage of the second channel. A small 0.22 mF ceramic capacitor is needed from this pin to ground to assure stability. 3 GND Power supply ground. Soldered to the copper plane allows for effective heat dissipation. 4 EN2 Driving EN2 over 0.9 V turns−on OUT2. Driving EN below 0.4 V turns−off the OUT2 and activates the active discharge. 5 IN 6 EN1 − EP Description Input pin common for both channels. It is recommended to connect 0.22 mF ceramic capacitor close to the device pin. Driving EN1 over 0.9 V turns−on OUT1. Driving EN below 0.4 V turns−off the OUT1 and activates the active discharge. Exposed pad must be tied to ground. Soldered to the copper plane allows for effective thermal dissipation. www.onsemi.com 2 NCV8152 ABSOLUTE MAXIMUM RATINGS Rating Symbol Value Unit VIN −0.3 V to 6 V V Output Voltage VOUT1, VOUT2 −0.3 V to VIN + 0.3 V or 6 V V Enable Inputs VEN1, VEN2 −0.3 V to VIN + 0.3 V or 6 V V Output Short Circuit Duration tSC Indefinite s Operating Ambient Temperature Range TA −40 to +125 °C TJ(MAX) 150 °C TSTG −55 to +150 °C ESD Capability, Human Body Model (Note 2) ESDHBM 2000 V ESD Capability, Machine Model (Note 2) ESDMM 200 V Input Voltage (Note 1) Maximum Junction Temperature Storage Temperature Range Stresses exceeding Maximum Ratings may damage the device.

Enable Turn−off www.onsemi.com 14 NCV8152 APPLICATIONS INFORMATION General disable state the device consumes as low as typ. 10 nA from the VIN. If the EN pin voltage >0.9 V the device is guaranteed to be enabled. The NCV8152 regulates the output voltage and the active discharge transistor is turned−off. The both EN pin has internal pull−down current source with typ. value of 300 nA which assures that the device is turned−off when the EN pin is not connected. In the case where the EN function isn’t required the EN should be tied directly to IN. The NCV8152 is a dual output high performance 150 mA Low Dropout Linear Regulator. This device delivers very high PSRR (75 dB at 1 kHz) and excellent dynamic performance as load/line transients. In connection with low quiescent current this device is very suitable for various battery powered applications such as tablets, cellular phones, wireless and many others. Each output is fully protected in case of output overload, output short circuit condition and overheating, assuring a very robust design. The NCV8152 device is housed in XDFN−6 1.2 mm x 1.2 mm package which is useful for space constrains application. Output Current Limit Output Current is internally limited within the IC to a typical 280 mA. The NCV8152 will source this amount of current measured with a voltage drops on the 90% of the nominal VOUT. If the Output Voltage is directly shorted to ground (VOUT = 0 V), the short circuit protection will limit the output current to 300 mA (typ). The current limit and short circuit protection will work properly over whole temperature range and also input voltage range. There is no limitation for the short circuit duration. This protection works separately for each channel. Short circuit on the one channel do not influence second channel which will work according to specification. Input Capacitor Selection (CIN) It is recommended to connect at least a 0.22 mF Ceramic X5R or X7R capacitor as close as possible to the IN pin of the device. This capacitor will provide a low impedance path for unwanted AC signals or noise modulated onto constant input voltage. There is no requirement for the min. or max. ESR of the input capacitor but it is recommended to use ceramic capacitors for their low ESR and ESL. A good input capacitor will limit the influence of input trace inductance and source resistance during sudden load current changes. Larger input capacitor may be necessary if fast and large load transients are encountered in the application. Thermal Shutdown When the die temperature exceeds the Thermal Shutdown threshold (TSD − 160°C typical), Thermal Shutdown event is detected and the affected channel is turn−off. Second channel still working. The channel which is overheated will remain in this state until the die temperature decreases below the Thermal Shutdown Reset threshold (TSDU − 140°C typical). Once the device temperature falls below the 140°C the appropriate channel is enabled again. The thermal shutdown feature provides the protection from a catastrophic device failure due to accidental overheating. This protection is not intended to be used as a substitute for proper heat sinking. The long duration of the short circuit condition to some output channel could cause turn−off other output when heat sinking is not enough and temperature of the other output reach TSD temperature. Output Decoupling (COUT) The NCV8152 requires an output capacitor for each output connected as close as possible to the output pin of the regulator. The recommended capacitor value is 0.22 mF and X7R or X5R dielectric due to its low capacitance variations over the specified temperature range. The NCV8152 is designed to remain stable with minimum effective capacitance of 0.15 mF to account for changes with temperature, DC bias and package size. Especially for small package size capacitors such as 0201 the effective capacitance drops rapidly with the applied DC bias. There is no requirement for the minimum value of Equivalent Series Resistance (ESR) for the COUT but the maximum value of ESR should be less than 2 W. Larger output capacitors and lower ESR could improve the load transient response or high frequency PSRR. It is not recommended to use tantalum capacitors on the output due to their large ESR. The equivalent series resistance of tantalum capacitors is also strongly dependent on the temperature, increasing at low temperature. Power Dissipation As power dissipated in the NCV8152 increases, it might become necessary to provide some thermal relief. The maximum power dissipation supported by the device is dependent upon board design and layout. Mounting pad configuration on the PCB, the board material, and the ambient temperature affect the rate of junction temperature rise for the part. For reliable operation, junction temperature should be limited to +125°C. The maximum power dissipation the NCV8152 can handle is given by: Enable Operation The NCV8152 uses the dedicated EN pin for each output channel. This feature allows driving outputs separately. If the EN pin voltage is <0.4 V the device is guaranteed to be disabled. The pass transistor is turned−off so that there is virtually no current flow between the IN and OUT. The active discharge transistor is active so that the output voltage VOUT is pulled to GND through a 50 W resistor.

This time is dependent on various application conditions such as VOUT(NOM), COUT, TA. The PMOS pass transistor has an inherent body diode which will be forward biased in the case that VOUT > VIN. Due to this fact in cases, where the extended reverse current condition can be anticipated the device may require additional external protection. PCB Layout Recommendations To obtain good transient performance and good regulation characteristics place input and output capacitors close to the device pins and make the PCB traces wide. In order to minimize the solution size, use 0402 capacitors. Larger copper area connected to the pins will also improve the device thermal resistance. The actual power dissipation can be calculated from the equation above (Equation 2). Expose pad should be tied the shortest path to the GND pin. Power Supply Rejection Ratio The NCV8152 features very good Power Supply Rejection ratio. If desired the PSRR at higher frequencies in the range 100 kHz − 10 MHz can be tuned by the selection of COUT capacitor and proper PCB layout.
