APL5521

APL5521 Dual-Channel, 3.3V/500mA and 2.5V/300mA Linear Regulator Features Fixed Output Voltage : VOUT1=3.3V/500mA VOUT2=2.5V/300mA Low Dropout Voltage (defined as the minimum www.DataSheet4U.com input/output voltage difference): Output 1 Dropout Voltage : 1.25V (at 500mA) Output 2 Dropout Voltage : 1.2V (at 300mA) Stable with 10uF Output Capacitor(at VOUT1) Stable with 10uF Output Capacitor(at VOUT2) No Protection Diodes Needed Built in Thermal Protection Built in Current Limit Protection Fast transient Response Short Setting Time SOP-8 Package Available General Description The APL5521 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 dropout voltage and faster transient response, which is critical for low voltage applications, the APL5221 has been optimized. The dropout voltages are guaranteed 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. The APL5521 regulator comes in a SOP-8 package.
