CM1582 Datasheet, PDF (1/11 Pages) List of Unclassifed Manufacturers – 3A LOW DROPOUT VOLTAGE REGULATOR

CM1582
3A LOW DROPOUT VOLTAGE REGULATOR
GENERAL DESCRIPTION
FEATURES
The CM1582 is a high performance low dropout regulator
!
rated for 3A 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 3A and low
quiescent current
Output Current is excess of 3A
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 CM1582 provides the device protections
including over current and thermal shutdown. The CM1582
series are ideal to the next generation microprocessor on
motherboards where both 5V and 3.3V are available.
