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. FAN2558: Fixed Output LDO with Power Good output FAN2558ADJ: Adjustable Output LDO with Power Good output FAN2559: Fixed Output LDO with Power Good output, Low Noise Available standard output voltages are 1.0, 1.2V, 1.3V, 1.5V, 1.8V, 2.5V, 3.3V, 3.5V, 3.6V, and 3.8V. Custom output volt- age options are also available.
