AX7905

AX7905/12 3-Terminal Fixed Negative Voltage Regulator  GENERAL DESCRIPTION The AX7905/12 series of fixed output negative voltage regulators are intended as complements to the popular TS7800 series device. These negative regulators are available in the same seven-voltage options as the AX7905/12 devices. In addition, one extra voltage option commonly employed in MECL systems is also available in the negative AX7905/12 Series. Available in fixed output voltage options from -5.0 to -24 volts, these regulators employ current limiting, thermal shutdown, and safe-area compensation--making them remarkably rugged under most operating conditions. With adequate heat sinking they can deliver output currents in excess of 1 ampere. This series is offered in 3-pin TO-220 and TO252 package.  FEATURES Output Voltage: -5 and -12V Output current up to 1A No external components required Internal thermal overload protection Internal short-circuit current limiting Output transistor safe-area compensation Output voltage offered in 4% tolerance  PIN ASSIGNMENT The packages of AX7905/12 are TO220-3L and TO252-3L; the pin assignment is given by: Top View 3 Metal Tap IN 2 1 TO252-3L Top View OUT IN(Tab) GND Name GND IN (Tab) OUT Grand Description Voltage Input Voltage Output 3 Metal Tap IN OUT IN(Tab) GND 2 1 TO220-3L 1/8 Axelite Confidential Materials, do not copy or distribute without written consent.
