TC57
3.4
Input Capacitor
The  addition  of  an  input  capacitor  further  reduces
output noise, and negates the effects of power supply
input impedance. A 10礔 (min) Tantalum capacitor is
recommended.
3.5
Shutdown Mode
The TC57 enters a low power shutdown mode when
the shutdown input (SHDN) is high. During shutdown,
the  regulator  is  disabled,  the  output  capacitor  is
discharged through the load, and supply current to the
TC57 decreases to less than 1礎(chǔ). Normal operation
resumes when SHDN is brought low. If the shutdown
mode is not used, SHDN should be tied to V
