(1) The Absolute Maximum power dissipation depends on the ambient temperature and can be calculated using the formula: PD = (TJ - TA) /
θJA, where TJ is the junction temperature, TA is the ambient temperature, and θ JA is the junction-to-ambient thermal resistance. The
364-mW rating appearing under Absolute Maximum Ratings for the SOT-23-5 package results from substituting the absolute-maximum
junction temperature, 150°C, for TJ, 70°C for TA, and 175°C/W for θJA. More power can be dissipated safely at ambient temperatures
below 70°C . Less power can be dissipated safely at ambient temperatures above 70°C. The absolute-maximum power dissipation can
be increased by 4.5 mW for each degree below 70°C, and it must be derated by 4.5 mW for each degree above 70°C.
(2) The human-body model is 100 pF discharged through a 1.5-kΩ resistor into each pin. The machine model is a 200-pF capacitor
discharged directly into each pin.

(1) All limits are specified. All electrical characteristics having room-temperature limits are tested during production with TA = 25°C or
correlated using Statistical Quality Control (SQC) methods. All hot and cold limits are specified by correlating the electrical
characteristics to process and temperature variations and applying statistical process control.
(2) The target output voltage, which is labeled VOUT(nom), is the desired voltage option.
(3) An increase in the load current results in a slight decrease in the output voltage and vice versa.
(4) Dropout voltage is the input-to-output voltage difference at which the output voltage is 100 mV below its nominal value.
(5) Short-circuit current is measured on input supply line after pulling down VOUT to 95% VOUT(nom)
.
(6) Specified by design. The capacitor tolerance should be ±30% or better over the full temperature range. The full range of operating
conditions such as temperature, dc bias and even capacitor case size for the capacitor in the application should be considered during
device selection to ensure this minimum capacitance specification is met. X7R capacitor types are recommended to meet the full device
temperature range.
(7) Turnon time is time measured between the enable input just exceeding VIH and the output voltage just reaching 95% of its nominal
value.
(8) The low and high thresholds are generated together. Typically a 2.6% difference is seen between these thresholds.

APPLICATION INFORMATION
EXTERNAL CAPACITORS
Like any low-dropout regulator, the LP3988-Q1 requires external capacitors for regulator stability. The LP3988-
Q1 is specifically designed for portable applications requiring minimum board space and smallest components.
These capacitors must be correctly selected for good performance.
INPUT CAPACITOR
An input capacitance of ≊ 1µF is required between the LP3988-Q1 input pin and ground (the amount of the
capacitance may be increased without limit).
This capacitor must be located a distance of not more than 1 cm from the input pin and returned to a clean
analog ground. Any good-quality ceramic, tantalum, or film capacitor may be used at the input.
Important: Tantalum capacitors can suffer catastrophic failures due to surge current when connected to a low-
impedance source of power (like a battery or a very large capacitor). If a tantalum capacitor is used at the input,
it must be specified by the manufacturer to have a surge-current rating sufficient for the application.
There are no requirements for the ESR on the input capacitor, but tolerance and temperature coefficient must be
considered when selecting the capacitor to ensure the capacitance is ≊ 1 µF over the entire operating
temperature range.
OUTPUT CAPACITOR
The LP3988-Q1 is designed specifically to work with very small ceramic output capacitors. A ceramic capacitor
(dielectric types Z5U, Y5V or X7R) in the 1-µF to 22-µF range with a 5-mΩ to 500-mΩ ESR range is suitable in
the LP3988-Q1 application circuit.
It may also be possible to use tantalum or film capacitors at the output, but these are not as attractive for
reasons of size and cost (see the CAPACITOR CHARACTERISTICS section).
The output capacitor must meet the requirement for minimum amount of capacitance and also have an
Equivalent Series Resistance (ESR) value which is within a stable range (5 mΩ to 500 mΩ).
NO-LOAD STABILITY
The LP3988-Q1 remains stable and in regulation with no external load. This is specially important in CMOS RAM
keep-alive applications.
CAPACITOR CHARACTERISTICS
The LP3988-Q1 is designed to work with ceramic capacitors on the output to take advantage of the benefits they
offer: for capacitance values in the range of 1 µF to 4.7 µF, ceramic capacitors are the smallest, least expensive
and have the lowest ESR values (which makes them best for eliminating high-frequency noise). The ESR of a
typical 1-µF ceramic capacitor is in the range of 20 mΩ to 40 mΩ, which easily meets the ESR requirement for
stability by the LP3988-Q1.
The ceramic capacitor's capacitance can vary with temperature. Most large-value ceramic capacitors (≊ 2.2 µF)
are manufactured with Z5U or Y5V temperature characteristics, which results in the capacitance dropping by
more than 50% as the temperature goes from 25°C to 85°C.
A better choice for temperature coefficient in a ceramic capacitor is X7R, which holds the capacitance within
±15%.
Tantalum capacitors are less desirable than ceramic for use as output capacitors because they are more
expensive when comparing equivalent capacitance and voltage ratings in the 1-µF to 4.7-µF range.
Another important consideration is that tantalum capacitors have higher ESR values than equivalent-size
ceramics. This means that while it may be possible to find a tantalum capacitor with an ESR value within the
stable range, it would have to be larger in capacitance (which means bigger and more costly ) than a ceramic
capacitor with the same ESR value. It should also be noted that the ESR of a typical tantalum will increase about
2:1 as the temperature goes from 25°C down to −40°C, so some guard band must be allowed.

ZHCSB96A –MARCH 2013–REVISED JULY 2013
ON/OFF INPUT OPERATION
The LP3988-Q1 is turned off by pulling the VEN pin low, and turned on by pulling it high. If this feature is not
used, the VEN pin should be tied to VIN to keep the regulator output on at all time. To assure proper operation,
the signal source used to drive the VEN input must be able to swing above and below the specified turnon/turnoff
voltage thresholds listed in the Electrical Characteristics section under VIL and VIH.
FAST ON-TIME
The LP3988-Q1 utilizes a speed-up circuit to ramp up the internal VREF voltage to its final value to achieve a fast
output turnon time.
