CM1581
5A LOW DROPOUT VOLTAGE
REGULATOR
GENERAL DESCRIPTION
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.
In addition, the CM1581 provides the device prot...
