PJ1537 Datasheet, PDF (1/3 Pages) List of Unclassifed Manufacturers – Dual 1A Low Dorpout Fixed Voltage Regulators

Preliminary
PJ1537
Dual 1A Low Dorpout Fixed Voltage Regulators
The PJ1537 provides 2 output voltage : 3.3V and either
2.5V or 1.8V fixed with 1.0A each output current
capability. These devices have been optimized for low voltage
where transient response and miniumum input voltage critical.
Current limit features protect the outputs against short
circuit currents. On-chip thermal limiting provides protection
against any combination of overload and ambient temperature
that would create excessive junction temperatures.
The PJ1537 series regulators are available in 5-lead
TO-263 power packages.
