Applications
The LM2937ES-8.0 is ideal for post-regulator applications in battery-powered and automotive systems where a stable 8V rail is required from a higher-voltage supply. It suits consumer electronics, industrial control boards, and embedded systems needing reliable LDO regulation with minimal heat dissipation. Its low dropout characteristic makes it well-suited for designs where input-output differential is small.

Frequently Asked Questions
What is the output voltage and current rating of the LM2937ES-8.0?
The LM2937ES-8.0 provides a fixed 8V output voltage with a maximum output current of 500mA (0.5A). The dropout voltage is typically 0.5V and no more than 1V at full load, allowing efficient regulation even when the input voltage is close to 9V.
What input voltage range does the LM2937ES-8.0 support?
The LM2937ES-8.0 accepts an input voltage from 10V minimum up to 26V absolute maximum. This wide input range makes it suitable for automotive 12V systems and industrial power supplies that may experience voltage transients above the nominal supply level.
What package does the LM2937ES-8.0 use, and is it RoHS compliant?
The LM2937ES-8.0 comes in a SOT-223 (JESD-30 code R-PSSO-G3) surface-mount package, which offers good thermal dissipation for a small footprint. Note that the Pbfree code is listed as No, indicating this variant is not lead-free; designers requiring RoHS compliance should select the LM2937ES-8.0/NOPB variant.
What are common applications for the LM2937ES-8.0?
Typical applications include 8V rail generation in automotive electronics, post-regulation in multi-rail power supplies, microcontroller and sensor supply circuits, and industrial control systems. Its low dropout performance and wide input range make it especially useful where the supply voltage only slightly exceeds 8V or fluctuates significantly.
