EC8803 Datasheet, PDF (1/16 Pages) E-CMOS Corporation – 4- Low 300mA Linear Regulator

4- Low 300mA Linear Regulator
EC8803
Description
The EC8803 is a 4-Low (Low-dropout, Low-noise,
Low-quiescent current, Low-cost) linear regulator
that operations in the input voltage range from
+2.2V to +7.0V and delivers 300mA output current.
The high-accuracy output voltage is preset at an
internally trimmed voltage 2.5V or 3.3V. Other output
voltages can be mask-optioned from 1.2V to 5.0V
with 100mV increment, except EC8803 which
has 2.85V output voltage.
The EC8803 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
EC8803 devices are available in SOT-23,
TSOT-23, SOT-89 and TO-92 packages.
