3-TERMINAL REGULATOR (-3.3V) SC1714 February 2, 1998 TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The SC1714 is a 3-terminal negative voltage regulator with an output voltage rated at 3.3V below the positive supply voltage. Designed to be an improved plug in replacement for the BA714, it offers a low typical supply current of 12µA, a high output current sinking capability of 5mA, and a low negative temperature coefficient. It also features output overload protection. The SC1714 is ideal as a power source for liquid crystal displays. FEATURES • Low power supply current. • Low negative TC. • High output sinking capability. • Ouput overload protection. APPLICATIONS • Printing calculators • Cameras • Voltage reference for instrumentation TYPICAL APPLICATION CIRCUIT ORDERING INFORMATION DEVICE (1) PACKAGE TO-92 SC1714ZS5 Note: (1) Add suffix ‘TR’ for tape and reel.
