AX1112

AX1112 1.2V 350mA Low Dropout Linear Regulator  GENERAL DESCRIPTION AX1112 is a low dropout positive fixed-mode regulator with minimum of 350mA 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 logic supply. AX1112 is also well suited for other applications such as VGA cards. AX1112 is guaranteed to have lower than 1.2V dropout at full load current making it ideal to provide well-regulated outputs.  FEATURES Fixed 1.2V + 2% output voltage Fast transient response Output current limiting Built-in thermal shutdown Good noise rejection Packages: SOT-23-3L  BLOCK DIAGRAM VÛmw`RyÑb€ Vin 3 2 Vout w.goftechm + + CURRENT LIMIT + 1.2V + Thermal Shutdown - 1 GND 1/6 Axelite Confidential Materials, do not copy or distribute without written consent.
