KF50BD-TR

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

The KF50BD-TR is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. It provides a stable 5V output with a maximum continuous current of 500mA. The device operates within an input voltage range up to 20V and features a typical dropout voltage of 0.4V at full load, reducing to 0.7V under specific conditions. It incorporates logic-controlled electronic shutdown functionality via Pin 5, which is TTL compatible. The component exhibits a quiescent current of approximately 1mA in active mode and includes internal protections against overcurrent and thermal overload. It is housed in an 8-SOIC surface-mount package.

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

Verify the exact suffix and package type during procurement to ensure compatibility with the 8-SOIC footprint. Confirm that the ordering code matches the specific output voltage and current rating required for the design. Check for RoHS compliance status as indicated in official documentation before finalizing supply chain agreements.

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

Select this component when a fixed 5V rail is needed with moderate current capability and space constraints favor an SOIC package. The inclusion of an enable pin allows for system-level power sequencing or standby modes. Ensure input voltage does not exceed the 20V absolute maximum rating and verify thermal dissipation requirements for the intended ambient temperature range.
