VDDOUT DC Output Voltage Normal mode, ILOAD = 100 mA 1.2 1.23 1.26 V
Standby mode 0
ILOAD Maximum DC Output Current 150 mA
CDIN Input Decoupling Capacitor (1) 4.7 µF
CDOUT Output Decoupling Capacitor (2) 1 µF
ESR 2 Ohm
tON Turn-on Time CDOUT = 1 µF, VDDOUT reaches DC output voltage 1 2.5 ms
Notes:
  1. 1.A 4.7 μF (±20%) or higher ceramic capacitor must be connected between VDDIN and the closest GND pin of the device. This large decoupling capacitor is mandatory to reduce startup current, improving transient response and noise rejection.
  2. 2.To ensure stability, an external 1 μF (±20%) output capacitor, CDOUT, must be connected between VDDOUT and the closest GND pin of the device. Solid tantalum and multilayer ceramic capacitors are suitable as output capacitors. A 100 nF bypass capacitor between VDDOUT and the closest GND pin of the device helps decrease output noise and improves the load transient response.

  1. 1.It is recommended to enable the Supply Monitor (see Table 58-9 Threshold selection).
  2. 2.The Supply Monitor operates down to 1.7V.
  3. 3.Once the Supply Monitor threshold is reached, it takes <200 µs to generate the internal reset of the device. The internal reset will remain active all the way until the POR becomes active.
  4. 4.The 200 us reset time parameter is for design guidance only, and is not tested in manufacturing.
