The Texas Instruments LM2937IMP-3.3/NOPB is a positive voltage regulator designed to supply up to 500 mA of load current. It features a low dropout voltage of typically 0.5V at full load and is trimmed for 5% tolerance under all operating conditions.
This regulator includes internal short circuit and thermal overload protection, as well as reverse battery protection and 60V input transient protection, making it suitable for automotive and industrial applications. The device is specified for operation over a wide temperature range of -40°C to 85°C.
The LM2937IMP-3.3/NOPB is available in a SOT-223-4 surface mount package. It requires an output bypass capacitor for stability, and the device is stable for output capacitor ESR below 3 Ω.
