1FEATURES
23• Qualified for Automotive Applications
• 200-mA Low-Dropout (LDO) Regulator DESCRIPTION
With Enable (EN) The TPS799xx family of low-dropout (LDO)
• Low I : 40 μA low-power linear regulators offers excellent ac
Q performance with very low ground current. High
• Multiple Output Voltage Versions Available: power-supply rejection ratio (PSRR), low noise, fast
– Fixed Outputs of V to V Using start-up, and excellent line and load transient
Innovative Factory EEPROM Programming response are provided while consuming a very low
– Adjustable Outputs from V to V 40-μA (typical) ground current. The TPS799xx is
stable with ceramic capacitors and uses an advanced
• High PSRR: 66 dB at 1 kHz BiCMOS fabrication process to yield a dropout
