TPS72730 250mA、超低 IQ、快速瞬态响应、射频低压降线性稳压器
TPS72730 描述
The TPS727xx family of low-dropout (LDO) linear regulators are ultralow quiescent current LDOs with excellent line and ultra-fast load transient performance and are designed for power-sensitive applications. The LDO output voltage level is preset by the use of innovative factory EEPROM programming. A precision bandgap and error amplifier provides overall 2% accuracy over load, line, and temperature extremes. The TPS727xx family is available in 1,5mm × 1,5mm SON and wafer chip-scale (WCSP) packages that make it ideal for handheld applications. This family of devices is fully specified over a temperature range of TJ = –40°C to +125°C.
