| tON | Turn-on time(5) | COUT= 2.2μF | – | 200 | μs |
Note:
- An X5R or X7R ceramic capacitor must be connected between VDD3V3 and the closest GND pin of the device. This decoupling capacitor is mandatory to reduce inrush current and to improve transient response and noise rejection.
- An external X5R or X7R capacitor must be connected between VDDOUT and the device's closest GND pin.
- Current needed to charge the external bypass/decoupling capacitor network.
- This regulator is designed to supply internal circuitry only. No external load authorized.
