NCP163AMX285TBG

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

The NCP163AMX285TBG is a fixed-output ultra-low noise LDO regulator from onsemi, providing a nominal 2.85 V output with a maximum current of 250 mA. It operates within an input voltage range of 2.2 V to 5.5 V and features ±2% accuracy over load and temperature. Key electrical characteristics include a typical quiescent current of 12 µA, dropout voltage of 95 mV at 250 mA, and power supply rejection ratio (PSRR) of 92 dB at 1 kHz. The device incorporates active discharge, thermal shutdown, and current limit protection.

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

Verify the specific ordering suffix TBG corresponds to the XDFN4 package and 5000-unit tape and reel shipping configuration. Confirm the 'A' option designation indicates the presence of the active discharge feature. Ensure compatibility with standard RoHS compliance requirements for the target assembly process.

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

Select this component when low noise and high PSRR are critical for powering RF front-ends or precision analog sections. The fixed 2.85 V output eliminates external resistor networks. Consider the XDFN4 package for space-constrained designs requiring efficient thermal dissipation via the exposed pad.

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

This part belongs to the NCP163 family of 250 mA LDO regulators designed for high-performance applications. The series offers various fixed voltage options ranging from 1.2 V to 5.3 V. It is available in WLCSP4, XDFN4, and SOT23-5L packages, catering to different footprint and thermal management needs in portable electronics.

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

Direct substitutes within the same family include NCP163AMX280TBG (2.8 V) and NCP163AMX290TBG (2.9 V). For non-active discharge variants, consider NCP163BMX285TBG. Verify pinout and thermal resistance specifications match the existing PCB layout.
