XC6205 Datasheet, PDF (6/13 Pages) Torex Semiconductor – Low ESR Cap. Compatible Output On/Off Control

XC6205 Series
Preliminary
High Speed LDO Regulators
Low ESR Cap. Compatible, Output On/Off Control
Minimum Operating Voltage
In order to stablize the IC's operations, an input voltage of more than 2.0V is needed. Should the input voltage be
less than 2.0V, the output voltage may not be regulated correctly. (Please refer to the graph data below.)
1 _{When VIN is less than 2.0V, the CE pin remains in standby mode.}
When VIN rises above 2.0V, the power supply will turn ON.
2 The input power supply will begin to rise after a few hundred µsec.
(Please also refer to the transient response characteristics.)

! Notes on Use
1 Please use this IC within the stated absolute maximum ratings.
The IC is liable to malfunction should the ratings be exceeded.
2 Where wiring impedance is high, operations may become unstable due to noise and/or phase lag
depending on output current. Please strengthen VIN and VSS wiring in particular.
3 Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
