200mA 低瞬态电流,超低噪声,高 PSRR 低压降线性稳压器

 

备选器件推荐

  • TLV758P  -  500-mA LDO regulator with lower IQ and 1% accuracy
  • TPS7A10  -  300-mA, low-IQ, LDO regulator in a small-size DSBGA package that supports lower input/output voltages and provides ultra-low dropout

描述

The TPS799 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 TPS799 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 TPS799 uses a precision voltage reference and feedback loop to achieve an overall accuracy of 2% over all load, line, process, and temperature variations. The TPS799 features inrush current protection when the EN toggle is used to start the device, immediately clamping the current.

All devices are fully specified over the temperature range of TJ = –40°C to 125°C, and offered in a low-profile, die-sized ball grid array (DSBGA) package, ideal for wireless handsets and WLAN cards.
