TPS79933DDCR Datasheet

Low Dropout Regulators - LDO


The TPS79933DDCR 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 TPS79933DDCR is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield dropout voltage typically 110mV at 200mA output. The TPS79933DDCR 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 and Wafer Chip-Scale packages (WCSP), ideal for wireless handsets and WLAN cards.
