Description

The TC56 is a low supply current (11A typical at V_OUT  = 3V), low dropout CMOS linear regulator, with a 10V maximum input voltage range. CMOS construction eliminates wasted ground current, typical of bipolar regulators, for greater system efficiencies and longer operating time in battery-powered systems. The TC56 enters shutdown mode when the shutdown control input (SHDN) is low. During shutdown, the regulator is shut off, and supply current falls to 0.1A maximum. Normal operation is restored when SHDN is returned to a logic high. Low current consumption, 10V supply tolerance and space-saving 5-Pin SOT-23A packaging makes the TC56 ideal for a wide variety of applications.
