NCV8720BMTW110TBG

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

The NCV8720BMTW110TBG is a fixed-output CMOS voltage regulator providing 1.1 V at up to 350 mA. It features an NMOS pass transistor with a separate bias supply (VBIAS) for ultra-low dropout performance, typically 110 mV at full load. The device operates within an input voltage range of 0.8 V to 5.5 V and a bias range of 2.4 V to 5.5 V. It offers ±2% output accuracy over temperature, low noise, and high PSRR. Packaged in a WDFN6 2 mm x 2 mm footprint with wettable flanks, it supports automotive applications requiring AEC-Q100 qualification.

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

Verify the specific ordering suffix 'W' indicates the wettable flank package variant required for enhanced optical inspection. Confirm that the 'NCV' prefix meets your project's automotive site and control change requirements. Check the manufacturer's discontinuation status for legacy variants before finalizing procurement plans.

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

Select this component when a separate bias rail is available to minimize dropout voltage below standard LDO limits. Ensure the application requires the specific 1.1 V fixed output or verify if other voltage options in the NCV8720 series better match the target load. Consider the WDFN6 package size constraints and thermal dissipation capabilities relative to the expected ambient operating conditions.

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

This part belongs to the NCV8720 family of very low dropout regulators designed for space-constrained, noise-sensitive environments. The family utilizes an NMOS pass transistor topology to achieve superior efficiency compared to PMOS alternatives. The NCV prefix specifically denotes devices qualified for automotive standards and unique manufacturing site controls.

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

Direct substitutes within the same family include NCV8720BMTW115TBG (1.15 V), NCV8720BMTW120TBG (1.20 V), and NCV8720BMTW130TBG (1.30 V). These share identical pinouts and packaging but differ in nominal output voltage. Verify that the alternative voltage level aligns with the downstream circuit requirements.
