FAN2558/FAN2559

180mA Low Voltage CMOS LDO

Features

General Description

• Fixed 1.0V, 1.2V, 1.3V, 1.5V, 1.8V, 2.5V, 3.3V, 3.5V, 3.6V,

3.8V and Adjustable Output

• Power Good Indicator with Open Drain Output

• 180mA Output Current

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.

• 100µA Ground Current

• C_bypassfor Low Noise Operation

• Fast Enable for CDMA Applications

• High Ripple Rejection

• Current Limit

• Thermal Shutdown

• Excellent Line and Load Regulation

• Requires Only 1µF Output Capacitor

• Stable with 0 to 300mΩ ESR

• TTL-level Compatible Enable Input

• Active Output Discharge

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

Applications

• Processor Power-up sequencing

• PDAs, Cell Phones

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.
