Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) to confirm lead-free status and RoHS compliance. Ensure the ordering part number matches the required tape-and-reel quantity specifications. Cross-reference the manufacturer datasheet revision date to validate electrical characteristics against current production standards before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 1.5A output current is required within a 36V input limit. The 1MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the thermal requirements of the 20-PowerTSSOP package align with the application's heat dissipation capabilities under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM3100 series of synchronous buck converters. It shares architectural similarities with the LM3102 and LM3103 models but offers distinct current ratings. The series utilizes Texas Instruments' SIMPLE SWITCHER design methodology to simplify power supply implementation for engineers requiring reliable DC-DC conversion solutions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM3100MH/NOPB is a tube-packaged equivalent of the same functional device. LM3102MHX/NOPB provides higher current capacity at 2.5A. LM3103MHX/NOPB offers lower current at 0.75A. Verify pin compatibility and thermal performance when substituting.
