NCV8720BMTW130TBG

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The NCV8720BMTW130TBG is a fixed-output CMOS voltage regulator from onsemi, providing a nominal output of 1.3 V at up to 350 mA. It utilizes an NMOS pass transistor and requires a separate bias supply (VBIAS) ranging from 2.4 V to 5.5 V. The device operates with an input voltage range of 0.8 V to 5.5 V and achieves ultra-low dropout performance, typically 110 mV at full load. It features ±2% accuracy over temperature, low noise, high PSRR, and built-in soft-start. Qualified under AEC-Q100 for automotive applications, it is housed in a compact WDFN6 package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix 'W' indicates the wettable flank option for enhanced optical inspection. Confirm the part status as active or discontinued via official channels before procurement. Ensure the design accommodates the required external ceramic capacitors for stability. Validate that the application environment meets the specified operating temperature range and electrical constraints.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a very low dropout voltage is critical for battery-operated systems requiring stable power delivery. The dual-input design allows independent optimization of the main input and bias rail voltages. Consider the WDFN6 package dimensions for space-constrained PCB layouts. Verify that the required output capacitance falls within the stable range of 2.2 µF to 10 µF for reliable loop stability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This device belongs to the NCV8720 series of CMOS voltage regulators designed for low-noise, space-constrained applications. The series offers various fixed output voltages and packaging options, including non-wettable and wettable flank variants. The NCV prefix denotes automotive qualification and unique site control change requirements, distinguishing it from standard commercial grade parts.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct replacements include other NCV8720 variants with different fixed output voltages, such as NCV8720BMTW120TBG or NCV8720BMTW150TBG, provided the voltage requirement changes. Non-wettable flank versions like NCV8720BMT130TBG are functionally identical but lack the wettable flank feature. Ensure any substitute maintains the same WDFN6 footprint and electrical characteristics.
