LP2950-50LPRE3

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

The LP2950-50LPRE3 is a micropower low-dropout voltage regulator manufactured by Texas Instruments. It provides a fixed 5V output with a maximum current of 100 mA. The device operates within an input voltage range of 2 V to 30 V and features a typical dropout voltage of 80 mV at full load. It maintains a line regulation of 0.2% and load regulation of 0.2%. The unit includes internal thermal overload protection and short-circuit current limiting. It functions reliably across an operating temperature range from -40°C to +125°C.

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

Verify the specific suffix 'RE3' against the manufacturer's latest documentation to confirm RoHS compliance status and lead-free pin availability. Ensure the ordering part number matches the exact package type and tape-and-reel specifications required for your assembly process. Cross-reference the datasheet revision date to confirm all electrical characteristics remain unchanged.

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

Select this component when a fixed 5V rail is required with minimal ground current draw. The TO-92 package suits through-hole designs where space allows. Verify that the input voltage never exceeds the 30 V absolute maximum rating. Consider the thermal dissipation capabilities of the TO-92 case under full load conditions to ensure junction temperatures remain within safe limits.

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

This device belongs to the LP2950 series of adjustable micropower voltage regulators. While many variants offer adjustable outputs, this specific model provides a fixed 5V reference. It shares the core architecture with the LP2951, which adds a shutdown control pin. The series is designed for applications prioritizing low power consumption over high current delivery.

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

The LP2950ACZ-5.0/NOPB offers identical electrical performance in a TO-92 package. For surface-mount requirements, the LP2950CDT-5.0/NOPB provides the same regulation in a DPAK format. Verify pin compatibility before substituting these alternatives.
