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.

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 ultra-

small, 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. X5R-

and 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

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.
