STLQ020
Description
The STLQ020 is a 200 mA low-dropout voltage regulator, able to work with an input
voltage ranging from 2 V to 5.5 V.
The typical dropout voltage at maximum load is 160 mV.
The ultra-low quiescent current, which is just 0.3 μA at no load, extends battery-life of
applications requiring very long standby time.
Even though the device intrinsic consumption is ultra-low, STLQ020 is able to provide
fast transient response and good PSRR performance, thanks to its adaptive biasing
circuit.
Enable pin puts the STLQ020 in shutdown mode, reducing total current consumption
to 5 nA.
The STLQ020 is designed to keep the quiescent current under control and at a low
value also during dropout operation, helping to extend even more the operating time
of battery- powered devices.
It also includes short-circuit constant-current limiting and thermal protection.
Several small package options are available.

Application information

Application information
7.1
External capacitors
The STLQ020 voltage regulator requires external low ESR capacitors to assure the control loop stability. These
capacitors must be selected to meet the requirements of minimum capacitance and equivalent series resistance
defined in the following chapters. Input and output capacitors should be located as close as possible to the
relevant pins.
Input capacitor
An input capacitor, with a minimum value of 1 μF, must be located as close as possible to the input pin of the
device and returned to a clean analog ground. A good quality, low-ESR ceramic capacitor is suggested. It helps to
ensure stability of the control loop, reduces the effects of inductive sources and improves ripple rejection.
Capacitance higher than 1 µF can be chosen in case of fast load transients in application.
Output capacitor
STLQ020 requires a low-ESR capacitor connected on its output, to keep the control loop stable and reduce the
risk of ringing and oscillations. The control loop is designed to be stable with any good quality ceramic capacitor
(such as X5R/X7R types) with a minimum value of 1 µF and equivalent series resistance in the [3 – 500 mΩ]
range. It is important to highlight that the output capacitor must maintain its capacitance and ESR in the stable
region over the full operating temperature, load and input voltage ranges, to assure stability. Therefore,
capacitance and ESR variations must be taken into account in the design phase to ensure the device works in the
expected stability region. There is no maximum limit to the output capacitance, provided that the above conditions
are respected.
7.2
Output voltage adjustment (adjustable version)
In the adjustable version, available on the DFN6-2x2 and SOT323-5L packages, the output voltage can be
adjusted to any voltage, starting from 0.8 V (VADJ) up to the input voltage minus the voltage drop (VDROP) across
the internal power pass element, by connecting a resistor divider between the ADJ pin and the output, allowing
the remote voltage sensing.
The resistor divider should be selected using the following equation:
Equation 1
VOUT = VADJ (1 + R1 / R2)
with VADJ = 0.8 V (typ.) and VOUT < VIN-VDROP(MAX)
For best accuracy and stability the resistor divider should be designed in order to allow that a current of at least
500 nA flows across it. The current flowing into the ADJ pin is typically less than 1 nA, therefore causing negligible
change in final the output voltage.
7.3
Enable pin operation
This is a logic control pin, CMOS level-compatible, which can be used to turn On/Off the regulator.It is active high,
so when it is pulled down, the device enters the shutdown mode, drastically reducing the current consumption, to
less just few nA.
Since it is not internally pulled-up, when the enable feature is not used, this pin must not be left floating. It can be
tied to VIN to keep the regulator output in ON state all the time.
To assure reliable operation, the signal source used to drive the EN pin, must be able to swing above and below
the specified thresholds listed in the electrical characteristics table (VEN).

Power dissipation
A proper PCB design is recommended, to ensure that the device internal junction temperature is kept below
125°C, in all the operating condition.
Depending on the package option, the thermal energy generated by the device flows from the die surface to the
PCB copper area through the package leads, solder bumps and/or exposed pad.

Protection features
The PCB copper area acts as a heat sink. The footprint copper pads should be as wider as possible to spread
and dissipate the heat to the surrounding environment. Thermal vias to the inner or backside copper layers
improve the overall thermal performance of the device.
The power dissipation of the LDO depends on the input voltage, output voltage and output current, and is given
by:
Equation 2
PD = (VIN -VOUT) IOUT
The junction temperature of the device is:
Equation 3
TJ_MAX = TA + RthJA x PD
where: TJ_MAX is the maximum junction of the die, 125 °C; TA is the ambient temperature; RthJA is the thermal
resistance junction-to-ambient.
With the above equation it is possible to calculate the maximum allowable power dissipation, therefore the
maximum load current for a certain voltage drop. Appropriate de-rating of the operating condition can be applied
accordingly.
7.5
Protection features
Current limit
The STLQ020 embeds a constant-current limit circuit, which acts in case of overload or short-circuit on the output,
clamping the load current to a safe value (typ. 380 mA).
Normal operation is restored if the overload disappears, but prolonged operation in current limit may lead to high
power dissipation inside the LDO and subsequently to thermal shutdown.
Thermal protection
An internal thermal feedback loop disables the output voltage if the die temperature reaches approximately
160 °C. This feature protects the device from excessive temperature that could lead to permanent damage to the
LDO.
Once the thermal protection is triggered and the device is shut down, normal operation is automatically recovered
if the die temperature falls below 140 °C (thermal protection hysteresis of 20 °C typically)
Important note: to keep the device power consumption below 500 nA in low load/no load condition, the internal
thermal protection is kept disabled for load current below 1 mA.
Current and thermal limit protections are designed to protect the LDO from excessive power dissipation and not
intended to replace a proper thermal and electrical design of the application.
Continuous operation above the maximum ratings may lead to permanent damage to the device.
