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

Verify the exact part number suffix against manufacturer documentation to ensure compatibility with specific package and tape-and-reel requirements. Confirm RoHS compliance status if required for your assembly process. Cross-reference the National Semiconductor (TI) datasheet for the most accurate ordering information and pinout configuration before procurement.

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

Select this component when a fixed 15 V output is required with moderate current demands up to 500 mA. Consider the TO-263 package for thermal management needs. Ensure the input voltage does not exceed the 26 V maximum rating. Evaluate the dropout voltage at full load to confirm it meets system headroom requirements compared to other LDO options.

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

This component belongs to the LM2937 family of 500 mA low dropout regulators. The 'ES' designation typically indicates a specific package type, such as TO-263, while '-15' specifies the 15 V output voltage.
