Line Regulation : 0.03% Typ. Low Dropout Voltage : 1.2V Typ. at IOUT =0.8A Current Limit : 1A Typ. at TJ=125 °C On-Chip Thermal Limiting : 150 °C Typ. Standard 3-pin SOT-223 and TO-252 Power Packages General Description The APL1117D/R is a low dropout three-terminal fixed 3.3V and 5.0V regulators with 1A output current capability. In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications , the APL1117D/R has been optimized. The dropout voltage is guaranteed at a maximum of 1.3V at 0.8A. Current limit is trimmed to ensure specified output current and controlled shortcircuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures. The APL1117D/R is available in the industry standard 3pin SOT-223 and TO-252 the low profile surface mount packages which can be used in applications where space is limited.
