LM2937 2.5-V and 3.3-V 400-mA and 500-mA Voltage Regulators Features 3 DescriptionThe LM2937-2.5 and LM2937-3.3 are positive voltage Operating Input Voltage Range: 4.75Vto26V regulators capableof supplying upto 500 mAof load• Fully Specifiedfor Operation Over −40°Cto 125°C current. Both regulators are ideal for convertinga• Output Currentin Excessof 500 mA (400 mAfor common 5-V logic supply, or higher input supply

low ESR chip capacitors.• Industrial Control Point-of-Load Regulation The regulators are also suited for automotive
applications, with built in protection from reverse

Device Information(1)* Requiredif the regulatoris located more than3inches from the power supply filter capacitors. Required for stability. COUT mustbeat least10 µF(over full expected operating temperature range) (1) Forall available packages, see the orderable addendumatand locatedas closeas possibleto the regulator. the endofthe datasheet.The equivalent series resistance, ESR,of this
capacitor maybeas highas3Ω.
