CM1581
5A LOW DROPOUT VOLTAGE REGULATOR
GENERAL DESCRIPTION
FEATURES
The CM1581 is a high performance low dropout regulator
rated for 5A output current with fixed 1.8V/2.5V/3.3V/5.0V and
adjustable output. It is designed for use in applications
requiring low dropout characteristics over the rated current
range.
When the second low-current input voltage is applied, the
dropout voltage can be as low as 100mV at light loads and up
to 500mV at maximum output current. On chip trimming
adjusts the reference voltage to 1%. These features are ideal
for low voltage microprocessor applications requiring a
regulated 1.8V to 3.6V power supply.

Input-Output differential of typical 500mV at 5A and low
quiescent current
Output Current is excess of 5A
Remote sense pin available
Reverse battery protection
Short Circuit Protection
Internal Thermal Overload Protection
5L TO-220 and 5L TO-263 package available
In addition, the CM1581 provides the device protections
including over current and thermal shutdown. The CM1581
series are ideal to the next generation microprocessor on
motherboards where both 5V and 3.3V are available.
