TPS73515DRBR

The TPS735 low-dropout (LDO), low-power linear regulator delivers excellent AC performance with ultralow ground current. It provides high PSRR, low noise, fast startup, and excellent line and load transient response while consuming only 45μA (typical) ground current. The TPS735 remains stable with ceramic capacitors and is manufactured using an advanced BiCMOS process, achieving a typical dropout voltage of 280mV at 500mA output current. Using a precision voltage reference and feedback loop, the TPS735 achieves 2% overall accuracy (VOUT>2.2V) across the full range of load, line, process, and temperature variations. The device is rated for TJ=-40°C to +125°C and is available in a thin 3mm×3mm SON-8 package and a 2mm×2mm WSON-6 package.
