TPS79912DRVR

TPS799 SBVS056L – JANUARY 2005 – REVISED FEBRUARY 2022 TPS799 200-mA, Low-Quiescent Current, Ultralow Noise, High-PSRR Low-Dropout Linear Regulator 1 Features 200-mA low-dropout regulator with EN Multiple output voltage versions available: – Fixed outputs of 1.2 V to 4.5 V – Adjustable outputs from 1.20 V to 6.5 V Inrush current protection with EN toggle Low IQ: 40 μA High PSRR: – 66 dB at 1 kHz – 51 dB at 10 kHz Stable with a low-ESR, 2-μF typical output capacitance Excellent load and line transient response 2% overall accuracy (load, line, and temperature) Very low dropout: 100 mV Packages: – 5-bump, thin, 0.97-mm × 1.34-mm DSBGA – 5-pin SOT-23-THIN – 6-pin WSON 2 Applications Base stations Smart phones EPOS Wearable electronics VCOs, RF Wireless LAN, Bluetooth® 3 Description The TPS799 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 response are provided while consuming a very low 40-μA (typical) ground current. The TPS799 is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a dropout voltage of typically 100 mV at a 200mA output. The TPS799 uses a precision voltage reference and feedback loop to achieve an overall accuracy of 2% over all load, line, process, and temperature variations. The TPS799 features inrush current protection when ...
