AX1007

AX1007 1A Low Dropout Linear Regulator  GENERAL DESCRIPTION AX1007 is a low dropout positive adjustable or fixed-mode 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 logic supply. AX1007 is also well suited for other applications such as VGA cards. AX1007 is guaranteed to have lower than 1.4V dropout at full load current making it ideal to provide well-regulated outputs of 1.25 to 5.0 with VOUT+1.4V to 12V input supply VOLTAGE.  FEATURES 1.4V maximum dropout at full load current Fast transient response Output current limiting Built-in thermal shutdown Good noise rejection MLCC Capacitors are available. 3-Terminal Adjustable or Fixed 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V Packages: SOT223, TO252 and SOT89.  BLOCK DIAGRAM VÛmw`RyÑb€ 2 VOUT VIN 3 w.goftech.com + + - CURRENT LIMIT + 1.25V + 1 GND (FIXED) Thermal Shutdown - 1 Adj 1/11 Axelite Confidential Materials, do not copy or distribute without written consent.
