FAN2558MP15X Datasheet PDF - Fairchild

●General Description

●The FAN2558/9 low voltage CMOS LDOs feature fixed or adjustable output voltage, 180mA load current, delayed power good output (open drain) and 1% output accuracy with excellent line and load regulation. An external bypass capacitor provides ultra-low noise operation.

●The FAN2558/9 low voltage LDOs incorporate both thermal shutdown and short circuit protection. Output is stable with a 1µF, low ESR capacitor. The FAN2558/9 family is available in 5-Lead SOT-23, 6-Lead SOT-23 and 2x2mm MLP-6 packages.
