TPS79325 超低噪声、高 PSRR、快速射频、高电平启用的 200mA 低压降稳压器
TPS79325 描述
The TPS793xx family of low-dropout (LDO) low-power linear voltage regulators features high power-supply rejection ratio (PSRR), ultralow-noise, fast start-up, and excellent line and load transient responses in NanoStar wafer chip scale and SOT23 packages. NanoStar packaging gives an ultrasmall footprint as well as an ultralow profile and package weight, making it ideal for portable applications such as handsets and PDAs. Each device in the family is stable, with a small 2.2uF ceramic capacitor on the output. The TPS793xx family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (for example, 112mV at 200mA, TPS79330). Each device achieves fast start-up times (approximately 50us with a 0.
