APL1541-KC-TU中文资料茂达电子数据手册PDF规格书

General Description

The APL1541 is a low dropout three-terminal adjustable 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 APL1541 has been optimized.

The device is available in an adjustable version and fixed output voltages of 3.3V, the output available voltage range is from 1.25~7.75V with an input supply below 12V. Dropout voltage is guaranteed at a maximum of 1.3V at 1A.
