DESCRIPTION

The A6345 is a low dropout (LDO) voltage regulator that can deliver up to 300mA of current while consuming only 3μ A of quiescent current (typical).

The input operating range is specified from 2.5V to 45V, making it an ideal choice for two to six or more primary cell battery-powered applications, 9V alkaline and one or two-cell Li-Ion-Power applications.

A6345 provides wide input voltage range and ensure

the stability of f ixed o utput v oltage of 1.8V, 2.5, 3.0,

3.3V and 5.0V

The A6345 is available in SOT-23, SOT-25 and SOT89-3 packages.
