GENERAL DESCRIPTION
The ADP7104 is a CMOS, low dropout linear regulator that
operates from 3.3 V to 20 V and provides up to 500 mA of
output current. This high input voltage LDO is ideal for
regulation of high performance analog and mixed signal
circuits operating from 19 V to 1.22 V rails. Using an
advanced proprietary architecture, it provides high power
supply rejection, low noise, and achieves excellent line and
load transient response with just a small 1 µF ceramic
output capacitor.
The ADP7104 is available in seven fixed output voltage options
and an adjustable version, which allows output voltages that
range from 1.22 V to VIN − VDO via an external feedback divider.

Figure 2. ADP7104 with Adjustable Output Voltage, 5 V
The ADP7104 output noise voltage is 15 μV rms and is inde-
pendent of the output voltage. A digital power-good output
allows power system monitors to check the health of the output
voltage. A user programmable precision undervoltage lockout
function facilitates sequencing of multiple power supplies.
The ADP7104 is available in 8-lead, 3 mm × 3 mm LFCSP
and 8-lead SOIC packages. The LFCSP offers a very compact
solution and also provides excellent thermal performance for
applications requiring up to 500 mA of output current in a
small, low-profile footprint.

1 Based on an end-point calculation using 1 mA and 300 mA loads. See Figure 6 for typical load regulation performance for loads less than 1 mA.
2 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 3.0 V.
3 Start-up time is defined as the time between the rising edge of EN to VOUT being at 90% of its nominal value.
4 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 5.0 V
output voltage is defined as the current that causes the output voltage to drop to 90% of 5.0 V, or 4.5 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;
Y5V and Z5U capacitors are not recommended for use with any LDO.
