LM2937-3.3 Datasheet (National Semiconductor) - 400mA and 500mA Voltage Regulators

LM2937-3.3, 400mA and 500mA Voltage Regulators

The LM2937-2.5 and LM2937-3.3 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.
