Package: SOT-223 Type

Manufacturer: National ( Texas Instruments )


LM2937IMPX-3.3 datasheet



The LM2937-2.5 and LM2937-3.3, LM2937IMPX-3.3 are positive voltage regulators capable of supplying up to 500 mA of load current. Both regulators are ideal for converting a common 5V logic
supply, or higher input supply voltage, to the lower 2.5V and 3.3V supplies to power VLSI ASIC’s and microcontrollers. Special circuitry has been incorporated to minimize the quiescent current to typically only 10 mA with a full 500 mA load current when the input to output voltage differential is greater than 5V.



1. Fully Specified for Operation Over -40°C to +125°C

2. Output Current in Excess of 500 mA (400mA for SOT-223 package)

3. Output Trimmed for 5% Tolerance Under All Operating Conditions

4. Wide Output Capacitor ESR Range, 0.01Ω up to 5Ω

5. Internal Short Circuit and Thermal Overload Protection

6. Reverse Battery Protection

7. 60V Input Transient Protection

8. Mirror Image Insertion Protection
