GENERAL DESCRIPTION
The ADP160/ADP161/ADP162/ADP163 are ultralow quiescent
current, low dropout, linear regulators that operate from 2.2 V
to 5.5 V and provide up to 150 mA of output current. The low
195 mV dropout voltage at 150 mA load improves efficiency and
allows operation over a wide input voltage range.
The ADP16x are specifically designed for stable operation with a
tiny 1 µF ± 30% ceramic input and output capacitors to meet
the requirements of high performance, space-constrained
applications.
The ADP160 is available in 15 fixed output voltage options,
ranging from 1.2 V to 4.2 V. The ADP160/ADP161 also include
a switched resistor to discharge the output automatically when
the LDO is disabled. The ADP162 is identical to the ADP160
but does not include the output discharge function.
The ADP161 and ADP163 are available as adjustable output voltage
regulators. They are only available in a 5-lead TSOT package.
The ADP163 is identical to the ADP161 but does not include
the output discharge function.
Short-circuit and thermal overload protection circuits prevent
damage in adverse conditions. The ADP160 and ADP162 are
available in a tiny 5-lead TSOT and a 4-ball, 0.5 mm pitch
WLCSP package for the smallest footprint solution to meet a
variety of portable power applications.

1 Accuracy when VOUT is connected directly to ADJ. When the VOUT voltage is set by external feedback resistors, the absolute accuracy in adjust mode depends on the
tolerances of resistors used.
2 Based on an end-point calculation using 0 μA and 150 mA loads.
3 Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage. This applies only for output
voltages above 2.2 V.
4 Start-up time is defined as the time between the rising edge of EN to VOUT being at 90% of its nominal value.
5 Current limit threshold is defined as the current at which the output voltage drops to 90% of the specified typical value. For example, the current limit for a 3.0 V
output voltage is defined as the current that causes the output voltage to drop to 90% of 3.0 V or 2.7 V.

1 The minimum input and output capacitance should be greater than 0.7 µF over the full range of operating conditions. The full range of operating conditions in the
application must be considered during device selection to ensure that the minimum capacitance specification is met. X7R and X5R type capacitors are recommended;
however, Y5V and Z5U capacitors are not recommended for use with any LDO.
