RoHS Compliant Product
A suffix of “-C” specifies halogen and lead-free
DESCRIPTION
The S5JGS1581D is a high performance positive voltage
Regulator is designed for use in applications requiring very low
Dropout voltage at 5 amps . When supplying 2.5V on motherboards
where both 5V and 3.3V supplies are available, the superior dropout
characteristics of the S5JGS1581D result in reduced heat dissipation
compared to regular LDOs, thus allowing heat sink size reduction.
Additionally, the S5JGS1581D provides excellent regulation over
Variations in line, load and temperature. Remote sense operation
allows compensating for trace, connector and other resistive losses.
Outstanding features include very low dropout performance at
Rates current, fast transient response ,remote sense, internal current
limiting, thermal shutdown and safe operating area protection of the
output device. The S5JGS1581D is a five terminal adjustable voltage
regulator available in the TO-252-5L package.

SENSE
, For S5JGS1581D V
ADJ
=0V.
3. For the adjustable device the minimum load current is the minimum current required to maintain regulation. Normally the current in the
resistor divider used to set the output voltage is select to meet the minimum load current requirement.
4. The control pin current is the drive current required for the output transistor. This current will track output current with a ratio of about
1:100.
5. The dropout voltage for the S5JGS1581D is caused by either minimum control voltage or minimum power voltage. The specifications
represent the minimum input/output voltage required to maintain 1% regulation.
