The LM2937ET3.3 from Texas Instruments is a positive voltage regulator designed to supply up to 500mA of load current. It utilizes a PNP power transistor, enabling a low dropout voltage characteristic, typically 0.5V at full rated load current.
This regulator features a maximum input voltage of 26V and a minimum input voltage of 6V. It offers fixed output voltage options including 2.5V, 3.3V, 5V, 8V, 10V, 12V, and 15V, with an accuracy of 5%. The device provides a typical noise level of 150 µVrms and a PSRR of 57 dB at 100 KHz. Its quiescent current is typically 2mA.
The LM2937ET3.3 is fully specified for operation over a wide temperature range of -40°C to 125°C. It includes internal short circuit and thermal overload protection, reverse battery protection, and 60V input transient protection. The regulator supports a wide output capacitor ESR range, up to 3 Ω.
Available in TO-263 (KTT), TO-220 (NDE), and SOT-223 (DCY) packages, this component is suitable for various power management applications requiring stable voltage regulation.
