available on pin n° 3 (TTL compatible). This
means that when the device is used as local
regulator, it is possible to put a part of the board in
standby, decreasing the total power consumption.
The LD2980 is designed to work with low ESR
ceramic capacitors. Typical applications are
cellular phone, laptop computer, personal digital
assistant (PDA), personal stereo, camcorder and
camera.
Description
The low drop-voltage and the ultra low quiescent
current make them suitable for low noise, low
power applications and in battery
poweredsystems. The quiescent current in sleep
mode is less than 1 µA when the INHIBIT pin is
pulled low. A shutdown logic control function is

Application notes
7.1
External capacitors
LD2980ABxx - LD2980Cxx
Like any low-dropout regulator, the LD2980 requires external capacitors for regulator
stability. This capacitor must be selected to meet the requirements of minimum capacitance
and equivalent series resistance. We suggest to solder input and output capacitors as close
as possible to the relative pins.
7.2
Input capacitor
An input capacitor whose value is 1 µF is required with the LD2980 (amount of capacitance
can be increased without limit). This capacitor must be located a distance of not more than
0.5" from the input pin of the device and returned to a clean analog ground. Any good quality
ceramic, tantalum or film capacitors can be used for this capacitor.
7.3
Output capacitor
The LD2980 is designed specifically to work with ceramic output capacitors. It may also be
possible to use Tantalum capacitors, but these are not as attractive for reasons of size and
cost. By the way, the output capacitor must meet both the requirement for minimum amount
of capacitance and ESR (equivalent series resistance) value. The Figure 4 and Figure 5
show the allowable ESR range as a function of the output capacitance. These curves
represent the stability region over the full temperature and IO range. Due to the different loop
gain, the stability improves for higher output versions and so the suggested minimum output
capacitor value, if low ESR ceramic type is used, is 1 µF for output voltages equal or major
than 3.8 V, 2.2 µF for output voltages from 2.85 to 3.3 V, and 3.3 µF for the other versions.
However, if an output capacitor lower than the suggested one is used, it’s possible to make
stable the regulator adding a resistor in series to the capacitor (see Figure 1 and Figure 2 to
choose the right value according to the used version and keeping in account that the ESR of
ceramic capacitors has been measured @ 100 kHz).
7.4
Important
The output capacitor must maintain its ESR in the stable region over the full operating
temperature to assure stability. Also, capacitor tolerance and variation with temperature
must be considered to assure the minimum amount of capacitance is provided at all times.
This capacitor should be located not more than 0.5" from the output pin of the device and
returned to a clean analog ground.
7.5
Inhibit input operation
The inhibit pin can be used to turn OFF the regulator when pulled low, so drastically
reducing the current consumption down to less than 1 µA. When the inhibit feature is not
used, this pin must be tied to VI to keep the regulator output ON at all times. To assure
proper operation, the signal source used to drive the inhibit pin must be able to swing above
and below the specified thresholds listed in the electrical characteristics section under VIH
VIL. Any slew rate can be used to drive the inhibit.

Application notes
Reverse current
The power transistor used in the LD2980 has not an inherent diode connected between the
regulator input and output. If the output is forced above the input, no current will flow from
the output to the input across the series pass transistor. When a VREV voltage is applied on
the output, the reverse current measured, according to the test circuit in Figure 22, flows to
the GND across the two feedback resistors. This current typical value is 160 µA. R1 and R2
resistors are implanted type; typical values are, respectively, 42.6 kΩ and 51.150 kΩ.

Package mechanical data
In order to meet environmental requirements, ST offers these devices in ECOPACK®
packages. These packages have a lead-free second level interconnect. The category of
second Level Interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOPACK specifications are available at: www.st.com.
