Description

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