AP1121 Datasheet | Anachip

Features - - - - - - - - General Description AP1121 series are low dropout positive regulator with minimum of 1A output current capability. The product is specifically designed to provide well-regulated supply for low voltage IC applications such as high-speed bus termination and low current 3.3V/2.5V or 3.3V/1.8V logic supply. AP1121 series are guaranteed to have <1.3V dropout at full load current making it ideal to provide well regulated outputs dual channels with up to 18V input supply. 1.3V maximum dropout at full load current Fast transient response Output current limiting for each channel. Built-in thermal shutdown each channel. Good noise rejection Dual output ch1=3.3V, ch2=2.5V (1.8V for B version) Pb-Free Packages: SOP-8L - Applications - - PC peripheral munication - Connection Diagram (Top View) VOUT1 1 VIN 2 VIN 3 VOUT2 4 AP1121 8 7 6 5 GND GND GND GND - Pin Descriptions NAME GND 3.3V(VOUT1) 2.5V/1.8V (VOUT2) VIN Ground The output of the regulator.
