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

Verify the exact part number suffix, such as #TRPBF or #TRMPBF, which indicates reel packaging specifications. Confirm the manufacturer is Analog Devices Inc. Ensure the input voltage does not exceed 45V and the output current remains within 100mA limits. Check for RoHS compliance if required by your assembly process.

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

Select this component when a fixed 3.3V output is required with minimal quiescent current. It is ideal for applications where noise sensitivity is critical due to its low noise profile. Consider the 45V input range for systems with varying supply voltages. The small DFN footprint makes it suitable for dense PCB layouts.

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

This part belongs to the LT3061 series, which includes adjustable versions like the LT3061IDCB. The -3.3 suffix specifically denotes the fixed 3.3V output variant. The series is known for its high PSRR and ability to drive large capacitive loads without instability, thanks to the active clamp feature.

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

Direct substitutes may include other micropower LDOs from Analog Devices with similar pinouts and electrical characteristics. Verify that any replacement supports the same 45V input range and 100mA output current. Ensure the alternative offers comparable noise performance and thermal dissipation capabilities in an 8-lead DFN package.
