The Texas Instruments LM2937IMP-3.3 is a 500mA positive voltage regulator designed for automotive and industrial applications. It features a low dropout voltage characteristic, typically 0.5V at full load, and a fixed output voltage of 3.3V.
This regulator is capable of supplying up to 500mA of load current and includes internal short circuit and thermal overload protection. It also provides 60V input transient protection, reverse battery protection, and mirror image insertion protection, making it suitable for harsh environments.
The LM2937IMP-3.3 operates over a wide temperature range of -40°C to 125°C. It requires an output bypass capacitor for stability and is specified for ESR values up to 3Ω, allowing for the use of low ESR chip capacitors. Available packages include TO-220, SOT-223, and TO-263.
Key electrical specifications include a maximum input voltage of 26V and a minimum input voltage of 6V. The output voltage is trimmed to a 5% tolerance under all operating conditions. Quiescent current is typically 10mA at full load.
The output voltage is 3.3V fixed.
The maximum output current is 500mA (0.5A).
The input voltage can range from 6V minimum to 26V maximum.
The device operates from -40°C to 125°C.
The LM2937IMP-3.3 is available in TO-220-3 (through-hole) and SOT-223-4 or TO-263-3 (surface-mount) packages.
The typical dropout voltage is 500mV at full rated load current.
Yes, the regulator can withstand input transients up to 60V.
