SNVS015F – FEBRUARY 1998 – REVISED NOVEMBER 2014 LM2937 2.5-V and 3.3-V 400-mA and 500-mA Voltage Regulators
1 Features 3 Description 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 5-V logic supply, or higher input supply
voltage, to the lower 2.5-V and 3.3-V supplies to
power very-large-scale integrations (VLSI) ASICs 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 5 V. 1 Operating Input Voltage Range : 4.75 V to 26 V
Fully Specified for Operation Over -40В°C to 125В°C …
