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 Bi CMOS fabrication process to yield a typical dropout voltage of 280 m V at 500m A 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.
