Description

This is 3.3V/500mA and 2.5V/300mA Linear Regulator. 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 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 ensu.
