SBVS310C July 2017 – June 2019 TLV743P
The TLV743P device uses an advanced internal control loop to obtain stable operation with the use of input or output capacitors. An output capacitance of 1 μF or larger generally provides good dynamic response. Use X5R- and X7R-type ceramic capacitors because these capacitors have minimal variation in value and equivalent series resistance (ESR) over temperature.
Although an input capacitor is not required for stability, increased output impedance from the input supply may compromise the performance of the TLV743P. Good analog design practice is to connect a 0.1-µF to 1-µF capacitor from IN to GND. This capacitor counteracts reactive input sources and improves transient response, input ripple, and PSRR. Use an input capacitor if the source impedance is greater than 0.5 Ω. Use a higher-value capacitor if large, fast, rise-time load transients are expected, or if the device is located several inches from the input power source.
