T6336A-2685WG

tm TE CH T6336A Two Channel Constant Current Regulator FEATURES • Two Channel Constant Current Regulator • Option Current: 260mA/85mA, 260mA/130mA, 240mA/120mA, 225mA/110mA GENERAL DESCRIPTION The T6336A low-dropout bias supply for white LED is a high-performance used in conventional white LED designs. The T6336A much lower bias variation with supply voltage variation, significantly lower dropout voltage and Low Shutdown Supply Current, and in some applications, significantly improved efficiency from DC 2.7V to 5V. The T6336A is available in TO-252 lead-free package. • Low Dropout Voltage • Low 0.1 uA Shutdown Supply Current • TO-252 lead-free Package • ESD Human Body Mode Over 5KV • 2.7V to 5V Supply Voltage Range • Build in Thermal Protect 160 °C APPLICATIONS • Flash Light • Lighting • Portable Communication Devices • Handheld Electronics • DC/DC LED driver PART NUMBER EXAMPLES Part no.
