Pin Description
PIN
NAME
FUNCTION
Supply Voltage Input. IN is connected to the drain of the internal 18mΩ MOSFET. Bypass IN with a
1–7
IN
transient voltage-suppressor diode to GND for clamping inductive kick transients in the case of fast
output short-circuit to GND.
Power-Supply Input. Connect V_CC to a voltage between 2.7V and 18V. Connect a Schottky diode (or
8
V_CC
10Ω resistor) from IN to V_CC and a 1µF bypass capacitor to GND to guarantee full operation in the event
V_IN collapses during a strong short from OUT to GND.
GATE of Internal MOSFET. During startup, a 5.7µA current is sourced to enhance the internal MOSFET
9
GATE with a 10V/ms slew rate. Connect an external capacitance from GATE to GND to reduce the output slew
rate during startup.
