Features General Description
The APL5835 is a 3-pin low dropout linear regulator with
2.0% accuracy of output voltage over line , load and
temperature variations . Dropout voltage at 450mA output current is less than 1.3V . Both output current limiting and thermal shutdown are built in to provide maximal protection to the APL5835 against fault conditions .
The over current and thermal shutdown circuits become
active when the current exceed 450mA , or the junction
temperature reach 150°C . Normal operation is recovered when junction temperature drops below 130°C .
Applications
• Low Dropout Voltage of 1.3V at 450mA
• Output Voltage Accuracy ±
2.0%
• Line Regulation - 3mV (typ.)
• Load Regulation - 13mV (typ.)
• Input Voltage Range up to 9V
• Internal Current Limiting and Thermal Shutdown
Protections
• Available Output V oltages -ADJ, 1.8V, 2.5V,
2.6V, 2.7V, 2.8V, 3.3V
• V arious SOT-89 and T O-92 Packages Available
•Voltage Regulator for CD-ROM Drivers
•Voltage Regulator for LAN Cards
•Wireless Communication Systems
•Portable Instrument
•Portable Consumer Equipment
•Low Voltage Systems
