MARKING

built−in low R

NMOS transistor for fast output capacitor

DS(on)

discharging as option. The device is composed of the voltage reference

unit, error amplifier, resistor divider for output voltage sensing or

precise output voltage setting. The current limit and thermal shutdown

makes the device very suitable for industrial applications and portable

communication equipments.
