LTC6655
pin FuncTions SHDN (Pin 1):
Shutdown Input. This active low input
VOUT_S (Pin 6):
VOUT Sense Pin. Connect this pin at powers down the device to <20µA. If left open, an internal the load and route with a wide metal trace to minimize pull-up resistor puts the part in normal operation. It is load regulation errors. This pin sinks 2mA. Output error recommended to tie this pin high externally for best is RTRACE • 2mA, regardless of load current. For load performance during normal operation. currents <100µA, tie directly to VOUT_F pin.
VIN (Pin 2):
Power Supply. Bypass VIN with a 0.1µF, or
VOUT_F (Pin 7):
VOUT Force Pin. This pin sources and larger, capacitor to GND. sinks current to the load. An output capacitor of 2.7µF to
GND (Pin 4):
Device Ground. This pin is the main ground 100µF is required. and must be connected to a noise-free ground plane.
GND (Pins 3, 5, 8):
Internal Function. Ground these pins.
