L78M05CDT-TR

Product Overview

The STMicroelectronics L78M05CDT-TR is a linear voltage regulator IC in a DPAK surface-mount package. It provides a fixed positive 5 V output from a single regulator channel and supports up to 500 mA output current. The device accepts input voltages up to 35 V and is specified for operation from 0°C to 150°C. Its package is TO-252-3, DPAK (2 Leads + Tab), SC-63, and its lifecycle status is Active.

Key Features

• Fixed positive 5 V output from one regulator channel
• Output current rating of 500 mA
• Maximum input voltage of 35 V
• Quiescent current of 6 mA
• Power supply rejection of 62 dB at 120 Hz
• Protection against over current, over temperature, and short circuit
• Operating temperature range of 0°C to 150°C
• Surface-mount DPAK package, TO-252-3, SC-63

Applications

• Regulating a 5 V supply for logic circuits, sensors, or small digital loads
• Providing a fixed 5 V rail from higher-voltage DC sources in board-level power sections
• Supplying 5 V to low-current peripheral devices where a fixed 5 V rail is required

Design & Procurement Notes

For board design, confirm that the input voltage remains within the 35 V maximum and that the load current stays at or below 500 mA. The 6 mA quiescent current should be considered in power budgeting. The DPAK package and 0°C to 150°C operating range support surface-mount layouts with thermal consideration for the tab and leads. The listed protection features address over current, over temperature, and short circuit, while the 62 dB PSRR at 120 Hz relates to input ripple rejection.
