TABLE 3-1:
3.1
The push-pull output pin is used to monitor the voltage
on the V
threshold voltage, the RESET output will be held in the
low state. As the V
the RESET output will remain in the low state for
300 ms and then change to the high state, indicating
that the voltage on the V

3.3
Connect GND to the negative side of the input and
output capacitor. Only the LDO internal circuitry bias
current flows out of this pin (200 µA maximum).
3.4
By connecting an external 10 nF capacitor (typical) to
the bypass input, both outputs (V
have less noise and improved Power Supply Ripple
Rejection (PSRR) performance. The LDO output
voltage start-up time will increase with the addition of
an external bypass capacitor. By leaving this pin
unconnected, the start-up time will be minimized.
