T he ADP1109 is a versatile step-up switching regulator. T he
device requires only minimal external components to operate as
a complete switching regulator.
T he ADP1109-5 can deliver 100 mA at 5 V from a 3 V input,
and ADP1109-12 can deliver 60 mA at 12 V from a 5 V input.
T he device also features a logic controlled shutdown capability
that when a logic low is applied it will shut the oscillator down.
T he 120 kHz operating frequency allows for the use of small
surface mount components.
T he gated oscillator capability eliminates the need for frequency
compensation.
