Low-Dropout Voltage Regulator (LDO) in 1,2-mm × 1,2-mm SON Package
FEATURES
DESCRIPTION
•
•
•
•
•
•
The TLV716 is a family of dual-channel, capacitorfree,150-mA, low-dropout (LDO) voltage regulators
with multiple fixed-output options available from 1.0 V
to 3.3 V. These devices provide an initial 1%
accuracy and 1.5% accuracy over temperature.
1
2
•
•
No Input or Output Capacitors Required
Inrush Current Control
Low Crosstalk
Accuracy: 1%
Input Voltage Range: 1.4 V to 5.5 V
Multiple Fixed-Output Voltage Combinations
Possible from 1.0 V to 3.3 V
Foldback Current-Limit Protection
Package: 1,2-mm × 1,2-mm SON-6 (DPQ)
The TLV716 family is designed to be stable with or
without an input or output capacitor. Eliminating the
output capacitor allows for a very small solution size.
The TLV716P series provides an active pull-down
circuit to quickly discharge the output voltage if the
application requires an output capacitor.
The device provides inrush current control during
device power-up and enabling. Inrush control
provides constant-current charging of the output load
during startup, thereby reducing the risk of an
undesired overcurrent fault from the input supply or
battery.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

APPLICATION INFORMATION
The TLV716 and TLV716P belong to a family of dual-channel, capacitor-free, 150-mA, low-dropout voltage
(LDO) regulators. These devices can be used with or without external capacitors and are available in a 1,2-mm ×
1,2-mm package, making these devices a very small solution size for dual-channel, low-dropout (LDO)
regulators. This family of LDO regulators offers current-limit and thermal protection, and is specified from –40°C
to +85°C. Figure 24 shows an application circuit for this family of devices.

Figure 24. Typical Application Circuit
CAPACITOR-FREE OPERATION
The TLV716 is stable without the use of input or output capacitors. This functionality results in a reduction of
component count, cost, and solution size. In addition, without the need of external capacitors, the TLV716 ultrasmall, 1,2-mm × 1,2-mm DPQ package optimizes the solution size for board space-constrained applications. To
optimize device ac performance, an input and output capacitor is recommended, as described in the Input and
Output Capacitor Requirements section.
INPUT AND OUTPUT CAPACITOR REQUIREMENTS
The TLV716 uses an advanced internal control loop to obtain stable operation both with or without the use of
input or output capacitors as high as 100-µF. The dynamic performance of the device is improved with the use of
an output capacitor. An output capacitance of 0.1 μF or larger generally provides good dynamic response. X5Rand X7R-type ceramic capacitors are recommended because these capacitors have minimal variation in value
and equivalent series resistance (ESR) over temperature.
Although an input capacitor is not required for stability, good analog design practice is to connect a 0.1-µF to
1-µF capacitor from IN to GND. This capacitor counteracts input source impedance and improves supply
transient response, input ripple, and PSRR. A higher value capacitor may be necessary if large, fast, rise-time
load transients are anticipated or if the device is located several inches from the input power source.
BOARD LAYOUT RECOMMENDATIONS TO IMPROVE PSRR AND NOISE PERFORMANCE
If used, place the input and output capacitors as close to the device pins as possible. To improve ac performance
(such as PSRR, output noise, and transient response), TI recommends that for VIN and VOUT, the ground planes
are connected only at the GND pin of the device. In addition, connect the ground connection for the output
capacitor directly to the GND pin of the device.

INTERNAL CURRENT LIMIT
The TLV716 has an internal foldback current limit that helps protect the regulator during fault conditions. The
current supplied by the device gradually reduces while the output voltage decreases. When the output is
connected to ground, the LDO supplies a typical current of 40 mA. When in current limit, the output voltage is not
regulated and VOUT = IOUT × RLOAD; see Figure 10 and Figure 11. The PMOS pass transistor dissipates [(VIN –
VOUT) × ILIMIT] until thermal shutdown is triggered and the device turns off. When the device cools down, the
internal thermal shutdown circuit turns on the device. If the fault condition continues, the device cycles between
current limit and thermal shutdown. See the Thermal Information section for more details.
The TLV716 PMOS pass element has a built-in body diode that conducts current when the voltage at OUT
exceeds the voltage at IN. This current is not limited, so if extended reverse voltage operation is anticipated,
external limiting to 5% of the rated output current is recommended. A small schottky diode connected with the
anode to OUT and the cathode to IN can accomplish this limiting.
SHUTDOWN
The enable pin (EN) is active high. The device is enabled when the EN pin goes above 0.9 V. This relatively low
value of voltage required to turn the LDO regulator on can be used to enable the device with the general-purpose
input/output (GPIO) of recent processors whose GPIO voltage is lower than traditional microcontrollers.
The device is turned off when the EN pin is held at less than 0.4 V. When shutdown capability is not required, the
EN pin can connected to the IN pin. The TLV716P will pull down the output with a 120Ω resistor when the EN pin
falls below 0.4 V.
DROPOUT VOLTAGE
The TLV716 and TLV716P use a PMOS pass transistor to achieve low dropout. When (VIN – VOUT) is less than
the dropout voltage (VDO), the PMOS pass device is in the linear region of operation and the input-to-output
resistance is the RDS(ON) of the PMOS pass element. VDO scales approximately with the output current because
the PMOS device behaves like a resistor in dropout.
As with any linear regulator, PSRR and transient response are degraded as (VIN – VOUT) approaches dropout.
UNDERVOLTAGE LOCKOUT (UVLO)
The TLV716 and TLV716P use an undervoltage lockout circuit (1.3 V, typical) to keep the output shut off until the
internal circuitry is operating properly.
THERMAL INFORMATION
Thermal protection disables the output when the junction temperature rises to approximately +158°C, allowing
the device to cool. When the junction temperature cools to approximately +140°C, the output circuitry is again
enabled. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection
circuit may cycle on and off. This cycling limits the dissipation of the regulator, protecting it from damage as a
result of overheating.
Any tendency to activate the thermal protection circuit indicates excessive power dissipation or an inadequate
heatsink. For reliable operation, junction temperature should be limited to +125°C maximum. To estimate the
margin of safety in a complete design, increase the ambient temperature until the thermal protection is triggered;
use worst-case loads and signal conditions. The ambient temperature at which thermal shutdown occurs on the
device is 33°C higher (158°C - 125°C) than the maximum recommended operating conditions.
The internal protection circuitry of the TLV716 and TLV716P is designed to protect against overload conditions.
This circuitry is not intended to replace proper PCB layout and heatsinking. Continuously running the device into
thermal shutdown degrades reliability.

POWER DISSIPATION
The ability to remove heat from a die is different for each package type, presenting different considerations in the
printed circuit board (PCB) layout. The copper PCB area around the device that is free of other components
moves the heat from the device to ambient air. Performance data for JEDEC-low and high-K boards are given in
the Thermal Information table. Using heavier copper increases effectiveness in removing heat from the device.
Power dissipation (PD) is equal to the product of the output current and the voltage drop across both output pass
elements, as shown in Equation 1:
PD = (VIN – VOUT1) × IOUT1 + (VIN – VOUT2) × IOUT2
(1)
The maximum ambient temperature that the device can operate within the maximum TJ operating temperature of
+125°C depends on the thermal impedance and the total power dissipated within the device. Figure 25 and
Figure 26 show maximum ambient temperature verses output current for two different LDO configurations.
Figure 25 shows the maximum ambient temperature with VIN = 3.3 V, VOUT1 = 1.8 V, and VOUT2 = 1.0 V versus
IOUT1. Figure 26 shows the maximum ambient temperature with VIN = 5.0 V, VOUT1 = 3.3 V, and VOUT2 = 1.8 V
versus IOUT1.
