GENERAL DESCRIPTION
The T6335A low-dropout bias supply for
white LED is a high-performance used in
conventional white LED designs.
The T6335A has lower bias variation with
supply voltage variation, significantly
lower dropout voltage Low Shutdown
Current in some applications, significantly
improved efficiency from DC 2.7V to 5V.
The T6335A is available in SOT-89 and
TO-252 lead-free package.
APPLICATIONS
• Flash Light
• Lighting
• Portable Communication Devices
• Handheld Electronics
• DC/DC LED driver
