3 Description
The TPS79901 family of low-dropout (LDO), low-
power linear regulators 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 TPS79901 is stable with ceramic capacitors and
uses an advanced BiCMOS fabrication process to
yield a dropout voltage of typically 100 mV at a
200-mA output. The TPS79901 uses a precision
voltage reference and feedback loop to achieve an
overall accuracy of 2% over all load, line, process,
and temperature variations. The TPS79901 features
inrush current protection when the EN toggle is used
to start the device, immediately clamping the current.
The TPS79901 is fully specified over the temperature
range of T_J = –55°C to +125°C, and offered in a low-
profile, ideal for wireless handsets and WLAN cards.
