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.
