200mA Low Dropout Regulator with EN
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.
Low IQ: 40µA
Multiple Output Voltage Versions Available:
– Fixed Outputs of 1.2V to 4.5V Using
Innovative Factory EEPROM Programming
– Adjustable Outputs from 1.20V to 6.5V
High PSRR: 66dB at 1kHz
