GENERAL DESCRIPTION
The AMS3107 series consists of positive fixed and adjustable voltage regulators ideally suited for use in battery-powered
systems. These devices feature very low quiescent current of 0.8mA or less when supplying 50mA loads. This unique
characteristic and the extremely low input-output differential required for proper regulation (0.2V for output currents of
100mA) make the AMS3107 ideal to use for standby power systems.
Internal circuitry of AMS3107 is protected from input fault conditions caused by reverse battery installation or input voltages
that exceed maximum rated input voltage. During line transients, such as load dump (40V) when the input voltage to the
regulator can momentarily exceed the specified maximum operating voltage, the regulator will automatically shut down to
protect both internal circuits and the load. The AMS3107 series also includes internal current limiting, thermal shutdown, and
is able to withstand temporary power-up with mirror-image insertion.
The AMS3107 is offered in 3 lead TO-92, 8 lead SOIC, SOT-89, SOT-223 and TO-252 packages.

Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. For guaranteed performance limits and associated test conditions, see
the Electrical Characteristics tables.
Note 2: To ensure constant junction temperature, low duty cycle pulse testing is used.
Note 3: Limits appearing in boldface type apply over the entire junction temperature range for operation. Limits appearing in normal type apply for TA = TJ = 25°C.
Note 4: The maximum allowable power dissipation is a function of the maximum junction temperature TJ(MAX), the junction-to ambient thermal resistance qJ-A and the
ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is calculated using:
TJ(MAX) - TA
P(MAX) =
qJ - A
Where the value of the junction-to-ambient thermal resistance are as follows: 195°C/W for TO-92 (N), 160°C/W for the SO-8 (S), 110°C/W for SOT-89 (L), 90°C/W
for SOT-223 and 80°C/W for TO-252.

APPLICATION NOTES
Most type of tantalum or electrolytic capacitor can be used in the
applications. A critical characteristic of the capacitors is an ESR
value of 5W or less and a resonant frequency above 500kHz. The
value of this capacitor can be increased without limits.
For higher loads, the value of the capacitor should be increased,
specialy when the output voltage is set for 2.5V or less. The
AMS3107 lowest fixed output voltage value is 2.0V.
Definition of Terms
Dropout Voltage: The input-output voltage differential at which
the circuit stops to regulate against further reduction in input
voltage. Measured when the output voltage has dropped 100mV
from the nominal voltage obtained at 1V input, dropout voltage is
dependent upon load current and junction temperature.
Input Voltage: The DC voltage applied to the input terminal
with respect to ground. Input-Output Differential: The voltage
difference between the unregulated input voltage and the
regulated output voltage for which the regulator will regulate.
Line Regulation: The change in output voltage for a change in
the input voltage. The line regulation is measured under
conditions of low dissipation or by using low duty cycle pulse
testing such that the average chip temperature is not significantly
affected.

Long term stability: Output voltage stability under accelerated
life-test conditions after 1000 hours with maximum rated voltage
and junction temperature.
Output Noise Voltage: The rms AC voltage at the output, with
constant load and no input ripple, measured over a specified
frequency range.
Minimum Load
Quiescent Current: That part of the positive input current that
does not contribute to the positive load current. The regulator
ground lead current.
Ripple Rejection: The ratio of the peak-to –peak input ripple
voltage to the peak-to-peak output ripple voltage at specified
frequency.
Temperature Stability of VO: The percentage change in output
voltage for a thermal variation from room temperature to either
temperature extreme.
In circuits using the fixed output voltage versions, minimum load
is not required. For circuits using the adjustable device, the value
of R1 and R2 should be chosen such, that a current of
approximately 40mA flows through the network. The reference
voltage (1.235V) is measured between the adjust pin and VOUT
.
The output voltage can be set by the two resistors R1 and R2
using the following equation:
R1 + R2
VO = VREFæ

External capacitor
The AMS3107 series require an output capacitor of 10mF or
greater to ensure device stability. Without the capacitor the
device may oscillate.
The value of R1 is recommended to be between 25kW to 30 kW,
and the value of R2 will set the output voltage.
