Description

The APL5521-KC-TU is a dual low dropout regulator with output 1 with 3.3V/0.5A and output2 with 2.5V/0.3A output capability. In order to obtain lower drop-out voltage and faster transient response, which is critical for low voltage applications, the APL5221 has been optimized. The dropout voltages are guaran teed at 1.25V at 0.5A for output1 and 1.2V at 0.3A for output 2. 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.

Description

The APL5151 / APL5152 / APL5153 / APL5154 is micropower, low noise, low drop-out linear regulator. Operate from 3V to 6V input voltage and deliver up to 150mA. Typical output noise is just 60uV RMS with the addition of an external 0.33uF bypass capacitor in BP pin and typical dropout voltage is only 220mV at 150mA loading. Designed for use in battery-powered system, the low 50uA quies cent current makes it an ideal choice. Design with an internal P-channel MOSFET pass transistor, the APL5151 / APL5152 / APL5153 / APL5154 maintains a low supply current, independent of the load current and dropout voltage. Other features include reverse current protection , thermal shutdown protection , current limit protection to ensure specified output current and controlled short-circuit current.
