APL1088
500mA Low Dropout Linear Regulator
Features
General Description
•
•
•
•
•
The APL1088 is a 3-pin low dropout linear regulator
with 2.0% accuracy of output voltage over line , load
and temperature variations. The output current capability of APL1088 is over 500mA. Dropout voltage
at 500mA output current is less than 1.5V(max). Both
output current limiting and thermal shutdown are built
in to provide maximal protection to the APL1088
against fault conditions. The over current and thermal shutdown circuits become active when the current exceed 500mA , or the junction temperature
reach 150°C. Normal operation is recovered when
junction temperature drops below 130°C.
Output Voltage Accuracy ± 2.0%
Line Regulation - 1mV (typ.)
Load Regulation - 6mV (typ.)
Input Voltage Range up to 9V
Internal Current Limiting and Thermal Shutdown Protections
