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 t o 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-22 0, TO-26 3 & T O-252 pa ckag es.
