TPS73418 单路输出 LDO、250mA、固定电压 (1.8V)、低静态电流、低噪声、高 PSRR
TPS73418 描述
The TPS734xx 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 44µA (typical) ground current. The TPS734xx is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a typical dropout voltage of 125mV at 250mA output. The TPS734xx 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 ThinSOT-23, 2mm × 2mm SON, and 3mm × 3mm SON packages that are ideal for wireless handsets, printers, and WLAN cards.
