General Description
The FAN2558/9 low voltage CMOS LDOs feature xed 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.
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.
