The EC8811 series is a low-dropout linear regulator
that operates in the input voltage range from +2.3V
to +7.0V and delivers 1.0A output current.
The EC8811 is available in two types, fixed
output voltage type and adjustable output voltage
type. The fixed output voltage type is preset at an
internally trimmed voltage 1.0V,1.2V,1.8V, 2.5V, or
3.3V. Other options 1.2V, 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 EC8811 (ADJ type) consists of a 1.25V
band-gap reference, an error amplifier, and a
P-channel pass transistor. Other features include
short-circuit protection and thermal shutdown
protection.
The EC8811 (Fixed type) consists of a 0.95V
band-gap reference, an error amplifier, and a
P-channel pass transistor. Other features include
short-circuit protection and thermal shutdown
protection. The EC8811 series devices are
available in SOT-223, TO-252, TO-263 packages.
