CMOS IC
DESCRIPTION
The UTC
L1186
is a COMS positive linear regulator. One of its
features is the very low quiescent current typical as low as 30μA and
its dropout voltage is extremely low with 600mA output current.
The internal circuit includes thermal shutdown and current
fold-back to prevent device failure when the circuit is operated in the
bad conditions.
In application, the UTC
L1186
needs a low noise, regulated
supply. For stable operation, the output capacitance value should be
2.2μF or more.
The UTC
L1186
is an ideal for battery applications, such as
instrumentations, portable electronics, wireless devices, cordless
phones, PC peripherals, and battery powered widgets.
