Functional Pin Description
Pin No. Pin Name Pin Function
Input Voltage. This pin connects to the source of the internal pass transistor that supplies
1 VIN current to the output pin. Bypass VIN to GND with a minimum 1uF ceramic capacitor. Place
the decoupling capacitor physically as close as possible to the device.
2 GND Ground.
3
EN
Enable Input. Pulling this pin below 0.35V turns the regulator off, reducing the quiescent
current to a fraction of its operating value. This pin is not available for 3-pin packages.
Feedback Pin (Adjustable Version). This pin is the non-inverting input of the error amplifier.
4B F The FB pin voltage is regulated to 0.8V reference voltage. Set the output voltage according
to VOUT = 0.8 x (R1 + R2)/ R1 (V). This pin is not internally connected for the fixed output version.
Output Voltage. This pin is power output of the device. A pull low resistance exists when the
5T
VOU
device is disabled by pulling low the EN pin. To maintain adequate transient response to large
load change, a minimum 1uF ceramic capacitor is required to reduce the effects of current
transients on VOUT.
