LM2937-2.5 - National Semiconductor

LM2937-2.5 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. Special circuitry has been incorporated to minimize the quiescent cur.
