GENERAL DESCRIPTION
The ADP7182 is a CMOS, low dropout (LDO) linear regulator
that operates from −2.7 V to −28 V and provides up to −200 mA
of output current. This high input voltage LDO is ideal for regulation of high performance analog and mixed signal circuits
operating from −27 V down to −1.2 V rails. Using an advanced
proprietary architecture, it provides high power supply rejection
and low noise, and achieves excellent line and load transient
response with a small 2.2 μF ceramic output capacitor.
The ADP7182 is available in fixed output voltage and an
adjustable version that allows the output voltage to range from
−1.22 V to −VIN + VDO via an external feedback divider.
Rev. M
The following fixed output voltages are available from stock: −5 V
(3 mm × 3 mm LFCSP), −1.8 V, −2.5 V, −3 V, −5 V (TSOT), −1.2 V,
−1.5 V, −2.5 V, −5 V (2.00 mm × 2.00 mm LFCSP). Additional
voltages are available by special order.
The ADP7182 regulator output noise is 18 μV rms independent
of the output voltage. The enable logic is capable of interfacing
with positive or negative logic levels for maximum flexibility.
The ADP7182 is available in 5-lead TSOT, 6- and 8-lead LFCSP
packages for a small, low profile footprint.

Based on an endpoint calculation using −1 mA and −200 mA loads. See Figure 10 for the typical load regulation performance for loads less than 1 mA.
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 below −3 V.
3
Start-up time is defined as the time between the rising edge of EN to VOUT being at 90% of the 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 V
output voltage is defined as the current that causes the output voltage to drop to 90% of −5 V, or −4.5 V.

The minimum input and output capacitance must be greater than 1.5 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.

Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
THERMAL DATA
Absolute maximum ratings apply individually only, not in
combination. The ADP7182 can be damaged when the junction
temperature limits are exceeded. Monitoring ambient temperature
does not guarantee that junction temperature (TJ) is within the
specified temperature limits. In applications with high power
dissipation and poor thermal resistance, the maximum ambient
temperature may have to be derated.
In applications with moderate power dissipation and low printed
circuit board (PCB) thermal resistance, the maximum ambient
temperature can exceed the maximum limit as long as the junction
temperature is within specification limits. The TJ of the device is
dependent on the ambient temperature (TA), the power dissipation
of the device (PD), and the junction-to-ambient thermal resistance
of the package (θJA).
Maximum TJ is calculated from the TA and PD using the formula
In applications where high maximum power dissipation exists,
close attention to thermal board design is required. The value of
θJA can vary, depending on PCB material, layout, and environmental conditions. The specified values of θJA are based on a
4-layer, 4 in. × 3 in. circuit board. See JESD51-7 and JESD51-9 for
detailed information on the board construction. For additional
information, see the AN-617 Application Note, MicroCSP™
Wafer Level Chip Scale Package.
ΨJB is the junction-to-board thermal characterization parameter
with units of °C/W. ΨJB of the package is based on modeling and
calculation using a 4-layer board. The JESD51-12, Guidelines for
Reporting and Using Electronic Package Thermal Information, states
that thermal characterization parameters are not the same as
thermal resistances. ΨJB measures the component power flowing
through multiple thermal paths rather than a single path as in
thermal resistance, θJB. Therefore, ΨJB thermal paths include
convection from the top of the package as well as radiation from
the package, factors that make ΨJB more useful in real-world
applications. Maximum junction temperature is calculated from
the board temperature (TB) and power dissipation using the
formula
TJ = TB + (PD × ΨJB)
See JESD51-8 and JESD51-12 for more detailed information
about ΨJB.
THERMAL RESISTANCE
θJA, θJC, and ΨJB are specified for the worst-case conditions, that is, a
device soldered in a circuit board for surface-mount packages.

ESD CAUTION
TJ = TA + (PD × θJA)
Junction-to-ambient thermal resistance (θJA) of the package is
based on modeling and calculation using a 4-layer board. The
junction-to-ambient thermal resistance is highly dependent
on the application and board layout.
