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 TJ = –55°C to +125°C, and offered in a low-profile, ideal for wireless handsets and WLAN cards.
