1.5A CMOS LDO
DESCRIPTION
The UTC L11815B is a positive, linear regulator. One of its
features is the very low quiescent current typically as low as 45μA
and the dropout voltage is extremely low.
The internal circuit includes thermal shutdown and current
fold-back mechanism to prevent device failure when the circuit is
operated in the bad conditions.
In application, the UTC L11815B needs a low noise and
regulated supply. For stability, the output capacitance value should be 4.7μF or more.
The UTC L11815B is an ideal for battery applications, such as
instrumentations, portable electronics, wireless devices, cordless
phones, PC peripherals, and battery powered widgets. The output
voltage values are set during manufacturing and their accuracy is trimmed to within 1.5%.
