The TC1300 combines a low dropout regulator and a
microcontroller reset monitor in an 8-Pin MSOP package.
Total supply current is 80 μA (typical), 20 to 60
times lower than bipolar regulators.
The TC1300 has a precise output with a typical accuracy
of ±0.5%. Other key features include low noise
operation, low dropout voltage and internal feedforward
compensation for fast response to step
changes in load. The TC1300 has both over-temperature
and over-current protection. When the shutdown
control (SHDN) is low, the regulator output voltage falls
to zero, RESET output remains valid and supply current
is reduced to 30 μA (typical). The TC1300 is rated
for 300 mA of output current and stable with a 1 μF output
capacitor.
An active-low RESET is asserted when the detected
voltage (VDET) falls below the reset voltage threshold.
The RESET output remains low for 300 msec (typical)
after VDET rises above reset threshold. The TC1300
also has a fast wake-up response time (10 μsec.,
typical) when released from shutdown.
