GENERAL DESCRIPTION
The ADP7104 is a CMOS, low dropout linear regulator that oper-
ates 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 archi-
tecture, 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 V IN ? V DO 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.
