APL1117D中文资料茂达电子数据手册PDF规格书

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 short circuit 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 3- pin SOT-223 and TO-252 the low profile surface mount

packages which can be used in applications where space is limited.
