Description
Programmable Current Limitation
The output limitation current can be set by
an external resistance (R_PCL). The R_PCL is
connected between the PCL terminal and
GND. If there is no need of setting a
current limit, connect the PCL terminal to
GND.
Output Terminal
Connect a capacitor between the Vout
terminal and GND as follows.
Vout≥2.4V: Capacitance ≥ 1μF
Vout<2.4V:Capacitance ≥ 2.2μF
GND Terminal
On/Off Control Terminal
The On/Off voltages are as follows:
V_Cont≥1.8V : ON
V_Cont≤0.35V : OFF
Pull-down resistance (500kΩ) is built-in.
Input Terminal
Connect a capacitor of 1.0F or higher
between the Vin terminal and GND.
