General Description
The G9815 series is a low supply current, high PSRR,
low noise, and low dropout linear regulator making
them ideal for battery applications. It is available in
TO-252, SOT-223 packages. The supply current at
no-load is 45µA. An over-temperature protection circuit
is built-in in the Device to prevent thermal overload.
And the G9815 is equipped with a short-circuit current
fold-back protection circuit to prevent from failure. The
G9815 is stable with an output capacitance of 4.7µF or
greater
