LM2937IMPX-10/NOPB

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

The LM2937IMPX-10/NOPB is a low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments, part of the LM2937 series. It provides a fixed positive output voltage of 10 V with a maximum output current capability of 500 mA. The device operates within an input voltage range up to 26 V and features a typical dropout voltage of 500 mV at full load. It includes internal protections against short circuits and thermal overload. The component is housed in a surface-mount SOT-223-4 package and is rated for operation over an extended temperature range from -40°C to +125°C.

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

Verify the manufacturer designation as Texas Instruments despite the National Semiconductor heritage, as TI acquired the product line. Confirm the specific suffix 'NOPB' indicates lead-free and RoHS compliance status according to the official datasheet. Ensure the SOT-223-4 package type matches the design requirements. Cross-reference the exact part number to distinguish between tube and reel packaging options available from distributors.

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

Select this component when a fixed 10 V output is required with moderate current demands up to 500 mA. Consider the LDO topology for applications where noise sensitivity is lower than in switching regulators but efficiency is secondary to simplicity. Evaluate the thermal dissipation capabilities given the SOT-223 package size and the expected voltage drop across the device. Verify that the input voltage does not exceed the 26 V maximum rating.
