CM1086 1.5A LOW DROPOUT VOLTAGE REGULATOR GENERAL DESCRIPTION The CM1086 is a high performance low dropout regulator rated for 1.5A output current with fixed 2.5V/3.3V and adjustable output. It is designed for use in applications requiring low dropout characteristics over the rated current range. On chip trimming adjusts the reference voltage to 1%. These features are ideal for low voltage microprocessor applications requiring a regulated 2.5V to 3.6V power supply. In addition, the CM1086 provides the device protections including over current and thermal shutdown. Also, reverse battery protection scheme limits the reverse current when the input voltage falls below the output. ! ! ! ! ! ! FEATURES !
