FAN1539/FAN1540
1A/1.3A, LDO With Low Quiescent Current
Features
• Very Low Ground Current (IGND = 1mA)
• Excellent Line Regulation
• Excellent Load Regulation
• Very Low Transient Overshoot
• Stable with low ESR Output Capacitor (ESR = 0m)
• Thermal Shutdown
• Current Limit
• Output Options: 3.3V and 1.8V
Applications
• Disk Drive Circuits
• Desktop Computers
• Laptop, Notebook Computers
• General purpose Three Terminal Regulator
Description
The FAN1539/FAN1540 series of high current LDO (1.0A
and 1.3A) has been developed for portable applications
where low quiescent current is an important requirement.
The device features excellent line and load transient response
which does not exceed 10% of nominal output value for full
operating temperature range even during power ON cycle
and short circuit removal. Internally trimmed, temperature
compensated bandgap reference guarantees 2.5% accuracy
for full range of input voltage, output current and tempera-
ture. Included on the chip are accurate current limit and ther-
mal shutdown protection. Device stability is achieved with
only two external low ESR ceramic capacitors.
The FAN1539/FAN1540 is available in thermally enhanced
3x3mm 6-lead MLP, 5x6mm 8-lead MLP package and
3-lead TO-252 packages. The 5x6mm MLP package version
features separate Kelvin sense pin for high precision applica-
tions.

Notes:
3. Junction to ambient thermal resistance, θ JA, is a strong function of PCB material, board thickness, thickness and number of
copper plains, number of via used, diameter of via used, available copper surface, and attached heat sink
characteristics.Thermal resistance( θJA ), VIN, IOUT must be chosen not to exceed TJ = 150°C.
4. Soldering temperature should be 260°C for 10 second after 240°C for 30 second in I.R. reflow using 60/40 solder. Maximum
rate of temperature rise is 3°C/SEC to within 100°C of the final temperature.
5. Using Mil Std. 883E, method 3015.7(Human Body Model) and EIA/JESD22C101-A (Charge Device Model).
