General Description

The TC56 is a low supply current (11

µA typical at

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 0.1

µA 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.
