AX1113

AX1113 400mA Low Dropout Linear Regulator  GENERAL DESCRIPTION AX1113 is a low dropout positive adjustable or fixed-mode regulator with minimum of 400mA 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 5V logic supply. AX1113 is also well suited for other applications such as VGA cards. AX1113 is guaranteed to have lower than 1.2V dropout at full load current.  FEATURES - 3-Terminal Adjustable or Fixed 1.8V, 3.3, 5.0V - Fast transient response - Output current limiting - Built-in thermal shutdown - Good noise rejection - Packages: SOT89-3L  BLOCK DIAGRAM Vin 3 VÛmw`RyÑb€ w.goftechm + + CURRENT LIMIT + Thermal Shutdown 1.2V + 2 Vout 1 ADJ (GND) 1/6 Axelite Confidential Materials, do not copy or distribute without written consent.
