GENERAL DESCRIPTION
The ADP120 and ADP120-1 are low quiescent current, low
dropout, linear regulators that operate from 2.3 V to 5.5 V and
provide up to 100 mA of output current. The low 100 mV
dropout voltage at 100 mA load improves efficiency and allows
operation over a wide input voltage range. The low 25 μA of
quiescent current at full load make the ADP120 and the
ADP120-1 ideal for battery-operated portable equipment.
The ADP120 and ADP120-1 are available in 16 fixed output
voltage options, ranging from 1.2 V to 3.3 V. The parts are
optimized for stable operation with small 1 ꢀF ceramic output
capacitors. The ADP120 and ADP120-1 deliver good transient
performance with minimal board area.
Short-circuit protection and thermal overload protection circuits
prevent damage in adverse conditions. The ADP120 is available
in a tiny 5-lead TSOT and the ADP120-1 is available in a 4-ball
0.4 mm pitch WLCSP for the smallest footprint solution to
meet a variety of portable applications.
