TYPICAL OPERATING CIRCUIT
The ADP667 is a low-dropout precision voltage regulator that
can supply up to 250 mA output current. It can be used to give
a fixed +5 V output with no additional external components or
can be adjusted from +1.3 V to +16 V using two external resistors. Fixed or adjustable operation is automatically selected via
the SET input. The low quiescent current (20 µA) in conjunction with the standby or shutdown mode (0.2 µA) makes this
device especially suitable for battery powered systems. The
dropout voltage when supplying 100 µA is only 5 mV allowing
operation with minimal headroom and prolonging the battery
useful life. At higher output current levels the dropout remains
low increasing to just 150 mV when supplying 200 mA. A wide
input voltage range from 3.5 V to 16.5 V is allowable.

CIRCUIT DESCRIPTION
The internal bandgap voltage reference is trimmed to 1.255 V
and is used as a reference input to the error amplifier A1. The
feedback signal from the regulator output is supplied to the
other input by an on-chip voltage divider or by two external
resistors. When the SET input is at ground, the internal divider
provides the error amplifier’s feedback signal giving a +5 V output. When SET is at more than 50 mV above ground, comparator C1 switches the error amplifier’s input directly to the SET
pin, and external resistors are used to set the output voltage.
The external resistors are selected so that the desired output
voltage gives 1.255 V at the SET input.
The output from the error amplifier supplies base current to the
PNP output pass transistor which provides output current. Up
to 250 mA output current is available provided that the device
power dissipation is not exceeded.

Comparator C2 compares the voltage on the Low Battery Input,
LBI, pin to the internal +1.255 V reference voltage. The output
from the comparator drives an open drain FET connected to the
Low Battery Output pin, LBO. The Low Battery Threshold
may be set using a suitable voltage divider connected to LBI.
When the voltage on LBI falls below 1.255 V, the open drain
output, LBO, is pulled low.
A shutdown (SHDN) input that can be used to disable the
error amplifier and hence the voltage output is also available.
The supply current in shutdown is less than 1 µA.

Shutdown Input (SHDN)
APPLICATIONS INFORMATION
Circuit Configurations
The SHDN input allows the regulator to be switched off with a
logic level signal. This will disable the output and reduce the
current drain to a low quiescent (1 µA maximum) current. This
is very useful for low power applications. Driving the SHDN input to greater than 1.5 V places the part in shutdown.
For a fixed +5 V output the SET input should be grounded, and
no external resistors are necessary. This basic configuration is
shown in Figure 2. The input voltage can range from +5.15 V
to +16.5 V, and output currents up to 250 mA are available
provided that the maximum package power dissipation is not
exceeded.
If the shutdown function is not being used, then SHDN should
be connected to GND.

ADP667
The ADP667 contains on-chip circuitry for low power supply or
battery detection. If the voltage on the LBI pin falls below the
internal 1.255 V reference, then the open drain output LBO will
go low. The low threshold voltage may be set to any voltage
above 1.255 V by appropriate resistor divider selection.

Output Voltage Setting
If the SET input is connected to a resistor divider network, the
output voltage is set according to the following equation:
V OUT =V SET ×
Since the LBI input leakage current is less than 10 nA, large values may be selected for R3 and R4 in order to minimize loading.
For example, a 6 V low threshold, may be set using 10 MΩ for
R3 and 2.7 MΩ for R4.

so in most applications fixed resistors will be suitable.

Dropout Detector
tained and large base current flows in the PNP output transistor
in an attempt to hold it fully on. For minimum quiescent current, it is therefore important that the input voltage is maintained higher than the desired output level. If the device is being
powered using a battery that can discharge down below the recommended level, there are a couple of techniques that can be
applied to reduce the quiescent current, but at the expense of
dropout voltage. The first of these is illustrated in Figure 6. By
connecting DD to SHDN the regulator is partially disabled with
input voltages below the desired output voltage and therefore
the quiescent current is reduced considerably.
The ADP667 features an extremely low dropout voltage making
it suitable for low voltage systems where headroom is limited. A
dropout detector is also provided. The dropout detector output,
DD, changes as the dropout voltage approaches its limit. This is
useful for warning that regulation can no longer be maintained.
The dropout detector output is an open collector output from a
PNP transistor. Under normal operating conditions with the input voltage more than 300 mV above the output, the PNP transistor is off and no current flows out the DD pin. As the voltage
differential reduces to less than 300 mV, the transistor switches
on and current is sourced. This condition indicates that regulation
can no longer be maintained. Please refer to Figure 10 in the
“Typical Performance Characteristics.” The current output can
be translated into a voltage output by connecting a resistor from
DD to GND. A resistor value of 100 kΩ is suitable. A digital
status signal can be obtained using a comparator. The on-chip
comparator LBI may be used if it is not being used to monitor a
battery voltage. This is illustrated in Figure 5.

Another technique for reducing the quiescent current near dropout is illustrated in Figure 7. The DD output is used to modify
the output voltage so that as VIN drops, the desired output voltage setpoint also drops. This technique only works when external resistors are used to set the output voltage. With VIN greater
than VOUT, DD has no effect. As VIN reduces and dropout is
reached, the DD output starts sourcing current into the SET
input through R3. This increases the SET voltage so that the
regulator feedback loop does not drive the internal PNP transistor as hard as it otherwise would. As the input voltage continues
to decrease, more current is sourced, thereby reducing the PNP
drive even further. The advantage of this scheme is that it maintains a low quiescent current down to very low values of VIN at
which point the batteries are well outside their useful operating
range. The output voltage tracks the input voltage minus the
dropout. The SHDN function is also unaffected and may be
used normally if desired.

Output Capacitor Selection
An output capacitor is required on the ADP667 to maintain
stability and also to improve the load transient response. Capacitor values from 10 µF upwards are suitable. All specifications are tested and guaranteed with 10 µF. Capacitors larger
than 10 µF will further improve the dynamic transient response
characteristics of the regulator. Tantalum or aluminum electrolytics are suitable for most applications. For temperatures below
about –25°C, solid tantalums should be used as many aluminum electrolytes freeze at this temperature.

POWER DISSIPATION
conditions is 700 mW which exceeds the maximum ratings. By
using a dropper resistor to drop 4 V, the power dissipation
requirement for the regulator is reduced to 300 mW which is
within the maximum specifications for the N-8 package at 85°C.
The resistor value is calculated as R = 4/0.1 = 40 Ω. A resistor
power rating of 400 mW or greater may be used.
The ADP667 can supply currents up to 250 mA and can operate with input voltages as high as 16.5 V, but not simultaneously.
It is important that the power dissipation and hence the internal
die temperature be maintained below the maximum limits. Power
Dissipation is the product of the voltage differential across the
regulator times the current being supplied to the load. The
maximum package power dissipation is given in the Absolute
Maximum Ratings. In order to avoid excessive die temperatures,
these ratings must be strictly observed.

The die temperature is dependent on both the ambient temperature and on the power being dissipated by the device. The internal die temperature must not exceed 125°C. Therefore, care
must be taken to ensure that, under normal operating conditions, the die temperature is kept below the thermal limit.

TJ = TA + PD (θJA)
Transient Response
The ADP667 exhibits excellent transient performance as illustrated in the “Typical Performance Characteristics.” Figure 12
shows that an input step from 10 V to 6 V results in a very small
output disturbance (50 mV). Adding an input capacitor would
improve this even more.
This may be expressed in terms of power dissipation as follows:
PD = (TJ – TA)/(θJA)
where:
TJ = Die Junction Temperature (°C)
PD = Power Dissipation (W)
Figure 13 shows how quickly the regulator recovers from an
output load change from 10 mA to 100 mA. The offset due to
the load current change is less than 1 mV.
θJA = Junction to Ambient Thermal Resistance (°C/W)
Monitored µP Power Supply
TA = Ambient Temperature (°C)
Figure 15 shows the ADP667 being used in a monitored µP
supply application. The ADP667 supplies +5 V for the microprocessor. Monitoring the supply, the ADM705 will generate a
reset if the supply voltage falls below 4.65 V. Early warning of
an impending power fail is generated by a power fail comparator
on the ADM705. A resistive divider network samples the preregulator input voltage so that failing power is detected while
the regulator is still operating normally. An interrupt is generated so that a power-down sequence can be completed before
power is completely lost. The low dropout voltage on the
ADP667 maximizes the available time to carry out the powerdown sequence. The resistor divider network R1 and R2 should
be selected so that the voltage on PFI is 1.25 V at the desired
warning voltage.
If the device is being operated at the maximum permitted ambient temperature of 85°C, the maximum power dissipation permitted is:
PD (max) = (TJ (max) – TA)/(θJA)
PD (max) = (125 – 85)/(θJA)
= 40/θJA
where:
θJA = 120°C/W for the 8-pin DIP (N-8) package
θJA = 170°C/W for the 8-pin SOIC (SO-8) package
Therefore, for a maximum ambient temperature of 85°C:
PD (max) = 333 mW for N-8
PD (max) = 235 mW for SO-8

At lower ambient temperatures the maximum permitted power
dissipation increases accordingly up to the maximum limits

The thermal impedance (θJA) figures given are measured in still

thereby reducing the effective thermal impedance.

High Power Dissipation Recommendations

Where excessive power dissipation due to high input-output
differential voltages and/or high current conditions exists, the
simplest method of reducing the power requirements on the
regulator is to use a series dropper resistor. In this way the
excess power can be dissipated in the external resistor. As an
example, consider an input voltage of +12 V and an output
voltage requirement of +5 V @ 100 mA with an ambient temperature of +85°C. The package power dissipation under these
