The TPS799 family of low-dropout (LDO), low-power

TPS79901DDCR 1• 200-mA Low-Dropout Regulator With EN

linear regulators offers excellent ac performance with

TPS79901DDCR • Multiple Output Voltage Versions Available: very low ground current. High power-supply rejection

– Fixed Outputs of 1.2 V to 4.5 V Using ratio (PSRR), low noise, fast start-up, and excellent

Innovative Factory EEPROM Programming line and load transient response are provided while

consuming a very low 40-μA (typical) ground current. – Adjustable Outputs from 1.20 V to 6.5 V

TPS79901DDCR • Inrush Current Protection with EN Toggle The TPS799 is stable with ceramic capacitors and

uses an advanced BiCMOS fabrication process to • Low IQ: 40 μA

yield a dropout voltage of typically 100 mV at a

• High PSRR: 66 dB at 1 kHz 200-mA output. The TPS799 uses a precision voltage

• Stable with a Low-ESR, 2-μF Typical Output reference and feedback loop to achieve an overall

Capacitance accuracy of 2% over all load, line, process, and

temperature variations. The TPS799 features inrush • Excellent Load and Line Transient Response

current protection when the EN toggle is used to start
