Overview
The TLV702 series, specifically the TLV70233DBVR, is a line of low-dropout (LDO) linear regulators produced by Texas Instruments. These regulators are designed for power-sensitive applications and are characterized by their low quiescent current, excellent line and load transient performance, and high power-supply rejection ratio (PSRR). The TLV702 series is ideal for battery-operated handheld equipment due to its low output noise, low dropout voltage, and precision bandgap and error amplifier, which provide an overall 2% output voltage accuracy.
