Input Voltage. Connect IN pins 1 and 2 together and bypass IN to GND with a 10FF ceramic capacitor as
close to the device as possible.
Current-Limit Setting. Drive ISET low to have a 200mA current limit. Drive ISET high to have a 400mA current
limit.
Ground
Active-Low Fault Open-Drain Output. FLAG goes low when the forward output current limit is exceeded for
longer than the blanking time, the reverse current limit is exceeded, the OVP threshold on IN is reached, or
the part goes into thermal shutdown. FLAG is high impedance when EN is low or a fault is not present.
Active-High Switch-Enable Input. Drive EN high to turn on the device. Drive EN low to turn off the device.
Output Voltage. Connect OUT pins 7 and 8 together and bypass OUT to GND with a 1FF ceramic capacitor
as close to the device as possible.
Exposed Pad. Connect EP to GND. For enhanced thermal dissipation, connect EP to a large copper ground
plane. Do not use EP as the sole ground connection.
