APPLICATIONS Wireless Handsets Smart Phones, PDAs MP3 Players ZigBee® Networks Bluetooth® Devices Li-Ion Operated Handheld Products WLAN and Other PC Add-on Cards TLV712xxDBV SOT23-5 (TOP VIEW) DESCRIPTION The TLV712xx series of low-dropout linear regulators (LDOs) are low quiescent current devices with excellent line and load transient performance. These devices provide sub-bandgap output voltages; that is, output voltages less than 1.2 V all the way down to 0.7 V. Therefore, these LDOs can be used to power processors with operating voltages less than 1.2 V. 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.
