8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.
8.1 Application Information
The TLV704 family of LDOs are designed for power-sensitive applications and feature low quiescent current. These devices pair well with low-power microcontrollers, such as the MSP430.
8.2 Typical Application
Figure 15. Typical Application
8.2.1 Design Requirements
Select the desired device based on the output voltage.
Provide an input supply with adequate headroom to account for dropout and output current to account for the GND terminal current, and power the load.
8.2.2 Detailed Design Procedure
8.2.2.1 Input and Output Capacitor Requirements
The TLV704 requires a 1-µF or larger capacitor connected between OUT and GND for stability. Ceramic or tantalum capacitors can be used. Larger value capacitors result in better transient and noise performance.
Although an input capacitor is not required for stability, when a 0.1-µF or larger capacitor is placed between IN and GND, it counteracts reactive input sources and improves transient and noise performance. Higher value capacitors are necessary if large, fast rise time load transients are anticipated.
