FSAR001 — AC-DC Linear Regulator
January 2011
FSAR001
AC-DC Linear Regulator
Features
High Output Voltage Accuracy: 2%
Output Voltage: 5V
Low Ground Current: < 2.0mA
Ultra-Fast Line and Load Transient Response
Hysteretic Thermal and Current-Limit Protections
Over-Voltage and Under-Voltage Protections
Ultra-Low Power Dissipation with No Load
Universal Input Range: 80~265V
RMS
No Inductor Required
Low Components and Cost
Description
FSAR001 is designed to replace capacitor-fed (“cap
dropper”) non-isolated power supplies, offering better
high-power conversion performance and high-energy
efficiency than a cap dropper solution. The appliance
needs no inductor, uses few components, and offers
lower cost.
FSAR001 integrates a 600V high-power device, startup
controller, voltage control circuit, synchronous circuit,
low dropout regulator, over-temperature protector, over-
voltage protector, under-voltage protector, and current-
limit circuit onto a monolithic IC.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.
