PRODUCT DESCRIPTION

Calogic’s CLM2815 is a low power 1.5A adjustable and fixed voltage regulator. The device requires 2 external resistors to set the output for the adjustable version. The CLM2815 has been designed for low voltage applications that require lower dropout and faster transient responses. The device is well suited to power a low voltage microprocessor that requires a low dropout and a fast transient response to regulate from +2.85V to 3.8V. The device is adjustable to 1.2 volts.

The product family offers full protection against over-current faults, reversed input polarity, reversed load insertion, and positive and negative transient voltage. On-chip trimming adjusts the reference voltage to 1% while delivering 1.5A output current.

Encapsulated in a 3-pin TO-220, TO-263 & TO-252 packages.
