TLV70030DDCR LDO Linear Regulator: Datasheet, Applications

Description

The TLV700 series of low-dropout (LDO) linear regulators are low quiescent current devices with excellent line and load transient performance. These LDOs are designed for power-sensitive applications.A precision bandgap and error amplifier provides overall 2% accuracy. Low output noise， very high power-supply rejection ratio (PSRR), and low dropout voltage make this series of devices ideal for most battery-operated handheld equipment. All device versions have thermal shutdown and current limit for safety.

FAQ

What is the use of LDO regulator?

LDO regulators are used to derive lower output voltages from a main supply or battery. The output voltage is ideally stable with line and load variations, immune to changes in ambient temperature, and stable over time.

 

What is line regulation in LDO?

Line regulation is a measure of the LDO's ability to maintain the specified output voltage with varying input voltage. Line regulation is defined as. Line regulation = ∆V_OUT/∆V_IN. Figure 7 shows the output voltage of the ADM7172 vs. input voltage at different load currents.

 

How to increase my LDO efficiency?

To have a high efficiency, drop out voltage and quiescent current must be minimized. In addition, the voltage difference between input and output must be minimized, since the power dissipation of LDO regulators accounts for the efficiency.
