The TLV702xx 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 a wide selection of battery-operated handheld equipment. All device versions have thermal shutdown and current limit for safety. Furthermore, these devices are stable with an effective output capacitance of only 0.1 F. This feature enables the use of cost-effective capacitors that have higher bias voltages and temperature derating. The devices regulate to specified accuracy with no output load. The TLV702xxP series also provides an active pulldown circuit to quickly discharge the outputs. The TLV702xx series of LDO linear regulators are available in SOT23-5 and 1,5mm SON-6 packages.

PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of the Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.
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.
XX(X) is the nominal output voltage. For output voltages with a resolution of 100 mV, two digits are used in the ordering number; otherwise, three digits are used (for example, = 4.75 V). P is optional; devices with P have an LDO regulator with an active output discharge. YYY is the package designator. Z is package quantity. Use "R" for reel (3000 pieces), and "T" for tape (250 pieces).
For the most current package and ordering information see the Package Option Addendum at the end of this document, or visit the device product folder at www.ti.com. Output voltages from in 50-mV increments are available. Contact factory for details and availability.
