LTC1517-5
PIN FUNCTIONS
VIN (Pin 1): Charge Pump Input Voltage. May be between
2.7V and 5V. VIN should be bypassed with a ≥ 3.3µF low
ESR capacitor as close as possible to the pin for best
performance.
GND (Pin 2): Ground. Should be tied to a ground plane for
best performance.
VOUT (Pin 3): Regulated Output Voltage. VOUT should be
bypassed with a ≥ 3.3µF low ESR capacitor as close as
possible to the pin for best performance.
C1 + (Pin 4): Charge Pump Flying Capacitor Positive
Terminal.
C1 – (Pin 5): Charge Pump Flying Capacitor Negative
Terminal.
