TPS79901 200mA 低静态电流、超低噪声、高 PSRR LDO
TPS79901 描述
The TPS799xx family of low-dropout (LDO) low-power linear regulators offer 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 response are provided while consuming a very low 40µA (typical) ground current. The TPS799xx is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield dropout voltage typically 100mV at 200mA output. The TPS799xx uses a precision voltage reference and feedback loop to achieve overall accuracy of 2% over all load, line, process, and temperature variations. It is fully specified from TJ = -40°C to +125°C and is offered in low profile ThinSOT23, Wafer Chip-Scale (WCSP), and 2mm × 2mm SON packages, ideal for wireless handsets and WLAN cards.
