GENERAL DESCRIPTION
The ADP130 is a low quiescent current, low dropout linear regu-
lator. It is designed to operate in dual-supply mode with an input
voltage as low as 1.2 V to increase efficiency and provide up to
350 mA of output current. The low 17 mV dropout voltage at
a 100 mA load improves efficiency and allows operation over
a wider input voltage range.
A dual-supply power solution typically improves conversion
efficiency over a single-supply solution because the higher VBIAS
supply powers the part, and the lower VIN supply delivers current
to the load. The power dissipated in the device is thereby reduced.
The ADP130 is optimized for stable operation with small 1 μF
ceramic output capacitors. The ADP130 delivers good transient
performance with minimal board area.

The ADP130 is available in the following 31 fixed output voltage
options:
0.80 V to 2.00 V in 50 mV steps
1.875 V, 2.25 V, 2.50 V, 2.775 V, 2.80 V, and 3.0 V
The ADP130 has a typical internal soft start time of 200 μs. Short-
circuit protection and thermal overload protection circuits
prevent damage in adverse conditions. The ADP130 is available
in a tiny 5-lead TSOT package for the smallest footprint solution to
meet a variety of portable power applications.

1 IVIN = IGND − IBIAS, where IGND is the current flowing from the GND pin.
2 Based on an endpoint calculation using 1 mA and 350 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 1.3 V.
4 Start-up time is defined as the time from 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 2.0 V
output voltage is defined as the current that causes the output voltage to drop to 90% of 2.0 V, or 1.8 V.

1 The minimum input and output capacitance should be >0.70 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. Y5V and
Z5U capacitors are not recommended for use with any LDO.
