General Description
The TC56 is a low supply current (11碌A(chǔ) 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 0.1碌A(chǔ) 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.
