Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP5900TL-2.7/NOPB is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 2.7V
• Output current rating of 150mA
• Maximum input voltage of 5.5V
• Voltage dropout specification of 0.15V @ 150mA
• Quiescent current of 50 µA
• Surface mount mounting type
• 4-DSBGA package family
• Operating temperature range of -40°C ~ 85°C
• Active product status
• ROHS3 compliance

The LP5900TLX-2.7/NOPB from National Semiconductor meets all these criteria and qualifies as a parametric equivalent. Packaging configuration differences (Tape & Reel versus Bulk) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the LP5900TL-2.7/NOPB and LP5900TLX-2.7/NOPB are active production devices with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on:
