1. General Description

The FS8860 is a low-dropout linear regulator that

operates in the input voltage range from +2.5V to

+7.0V and delivers 1.0A output current.

The FS8860 is available in two types, fixed output

voltage type or adjustable output voltage type. The

fixed output voltage type is preset at an internally

trimmed voltage 1.8V, or 3.3V. Other options 1.5V,

2.85V, 3.0V and 3.6V are available by special order

only. The output voltage range of the adjustable type

is from 1.25V to 5V.

The FS8860 consists of a 1.25V bandgap reference,

an error amplifier, and a P-channel pass transistor.

Other features include short-circuit protection and

thermal shutdown protection. The FS8860 devices

are available in SOT-223 packages.
