Ceramic capacitors are recommended. For the best performance all the capacitors should be connected to the NCP120 respective pins directly in the device PCB copper layer, not through vias having not negligible impedance. When using small ceramic capacitor, their capacitance is not constant but varies with applied DC biasing voltage, temperature and tolerance. The effective capacitance can be much lower than their nominal capacitance value, most importantly in negative temperatures and higher LDO output voltages. That is why the recommended Output capacitor capacitance value is specified as Effective value in the specific application conditions. The NCP120 dual−rail very low dropout voltage regulator is using NMOS pass transistor for output voltage regulation from VIN voltage. All the low current internal controll circuitry is powered from the VBIAS voltage. The use of an NMOS pass transistor offers several advantages in applications. Unlike a PMOS topology devices, the output capacitor has reduced impact on loop stability. VIN to VOUT operating voltage difference can be very low compared with standard PMOS regulators in very low VIN applications. The NCP120 offers smooth monotonic start-up. The controlled voltage rising limits the inrush current. The Enable (EN) input is equipped with internal hysteresis. NCP120 is a Fixed Voltage linear regulator. Dropout Voltage Because of two power supply inputs VIN and VBIAS and one VOUT regulator output, there are two Dropout voltages specified. The first, the VIN Dropout voltage is the voltage difference (VIN – VOUT) when VOUT starts to decrease by percents specified in the Electrical Characteristics table. VBIAS is high enough, specific value is published in the Electrical Characteristics table. The second, VBIAS dropout voltage is the voltage difference (VBIAS – VOUT) when VIN and VBIAS pins are joined together and VOUT starts to decrease. Enable Operation The enable pin will turn the regulator on or off. The threshold limits are covered in the electrical characteristics table in this data sheet. If the enable function is not to be used then the pin should be connected to VIN or VBIAS. Current Limitation The internal Current Limitation circuitry allows the device to supply the full nominal current and surges but protects the device against Current Overload or Short. Thermal Protection Internal thermal shutdown (TSD) circuitry is provided to protect the integrated circuit in the event that the maximum junction temperature is exceeded. When TSD activated , the regulator output turns off. When cooling down under the low temperature threshold, device output is activated again. This TSD feature is provided to prevent failures from accidental overheating. Input and Output Capacitors The device is designed to be stable for ceramic output capacitors with Effective capacitance in the range from 1 mF to 10 mF. The device is also stable with multiple capacitors in parallel, having the total effective capacitance in the specified range. www.onsemi.com 6 NCP120 ORDERING INFORMATION Nominal Output Voltage Marking Marking Rotation NCP120AMX080TCG 0.80 V A 180° NCP120AMX105TCG 1.05 V D 180° NCP120AMX110TCG (Note 6) 1.10 V E 180° NCP120AMX115TCG 1.15 V F 180° NCP120AMX120TCG 1.20 V J 180° NCP120AMX150TCG 1.50 V K 180° NCP120AMX180TCG 1.80 V L 180° NCP120AMX210TCG 2.10 V P 180° NCP120BMX080TCG 0.80 V A 270° NCP120BMX105TCG 1.05 V D 270° NCP120BMX110TCG 1.10 V E 270° NCP120BMX115TCG 1.15 V F 270° NCP120BMX120TCG 1.20 V J 270° NCP120BMX150TCG 1.50 V K 270° NCP120BMX180TCG 1.80 V L 270° NCP120BMX210TCG 2.10 V P 270° Device Option Package Shipping† XDFN6 (Pb−Free) 3000 or 5000 / Tape & Reel (Note 6) Output Active Discharge Non−Active Discharge †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.
