Description

The TPS735 low-dropout (LDO), low-power linear regulator offers excellent AC performance with very low ground current. High power-supply rejection ratio (PSRR), low noise, fast start-up, and excellent line and load transient responses are provided while consuming a very low 45-µA (typical) ground current. The TPS735 device is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a typical dropout voltage of 280 mV at 500-mA output. The TPS735 device uses a precision voltage reference and feedback loop to achieve overall accuracy of 2% (VOUT> 2.2 V) over all load, line, process, and temperature variations. This device is fully specified from TJ= –40°C to +125°C and is offered in a low-profile, 3 mm × 3 mm SON-8 package and a 2 mm × 2 mm WSON-6 package.
