NCP163AMX330TBG

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

The NCP163AMX330TBG is a fixed-output low dropout regulator providing 3.3 V at up to 250 mA. It operates within an input voltage range of 2.2 V to 5.5 V and features ultra-low noise (6.5 µVRMS) and high PSRR (92 dB). Quiescent current is typically 12 µA with a standby current of 0.1 µA. The device includes active discharge, soft-start, thermal shutdown, and current limit protection. It is housed in an XDFN4 package and functions reliably across temperatures from -40°C to +125°C.

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

Verify the specific suffix 'MX' confirms the XDFN4 package type and '330' indicates the 3.3 V fixed output. Confirm the 'A' designation corresponds to the version with active discharge functionality. Ensure compatibility with the required 1 µF ceramic output capacitor for stability. Check RoHS compliance status if required for your manufacturing process.

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

Select this component when ultra-low noise and high PSRR are critical for RF or precision analog signal integrity. The 250 mA output capability supports moderate load requirements. The XDFN4 package offers a compact footprint suitable for space-constrained mobile designs. Verify that the input voltage remains within the 2.2 V to 5.5 V operational range for proper regulation.

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

This part belongs to the NCP163 family of next-generation LDO regulators. The series is engineered specifically for applications demanding minimal power supply interference. Other variants in the family offer different output voltages and package options such as WLCSP4 and SOT23-5L, maintaining consistent electrical characteristics across the lineup.

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

Direct substitutes include other NCP163 variants with different output voltages or packages, such as NCP163AMX180TBG for 1.8 V output. Cross-family replacements require verification of pinout compatibility, noise specifications, and package dimensions.
