The TLV767 is a wide input linear voltage regulator supporting an input voltage range from 2.5 V to 16 V and up to 1 A of load current. The output range is from 0.8 V to 6.6 V or up to 14.6 V in the adjustable version.Additionally, the TLV767 has a 1% output accuracy that can meet the needs of low voltage microcontrollers (MCUs) and processors.The TLV767 is designed to have a much lower IQ than traditional wide-VIN regulators, thus making the device well positioned to meet the needs of increasingly stringent standby power requirements. When disabled, the TLV767 draws only 1.5 µA of IQ.The internal soft-start time and foldback current limit reduce inrush current during start up, thus minimizing input capacitance.Wide bandwidth PSRR performance is greater than 70 dB at 1 kHz and 46 dB at 1 MHz, which helps attenuate the switching frequency of an upstream DC/DC converter and minimizes post regulator filtering. To allow for more flexibility, the TLV767 has both fixed and adjustable versions.The TLV767 is available in a 6-pin, 2-mm × 2-mm WSON (DRV), an 8-pin 3-mm x 3-mm HVSSOP (DGN), and a 5-pin 2.9-mm x 1.6-mm SOT-23 (DBV) package.
