Adjustable and fixed positive-voltage low-dropout linear regulator

The TLV767 from Texas Instruments is a wide input linear voltage regulator supporting an input voltage range from 2.5 to 16V and up to one amp of load current. The output range is from 0.8V to 6.6V or up to 13.6V in the adjustable version. Additionally, the TLV767 has a one percent 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 1.5µA of IQ.

The internal soft-start time and foldback current limit reduce inrush current during startup, thus minimising input capacitance.

Wide bandwidth PSRR performance is greater than 70 dB at 1kHz and 46 dB at 1MHz, which helps attenuate the switching frequency of an upstream DC/DC converter and minimises post regulator filtering. To allow for more flexibility, the TLV767 has both fixed and adjustable versions.

The TLV767 is available in a six-pin two by two millimetre WSON (DRV) package.
