EUP7917-300mA,低噪声,低压差线性稳压器


EUP7917-300mA,低噪声,低压差线性稳压器 DataSheet 

概述

EUP7917是一款为超低噪声优化设计的高效CMOS线性稳压器,它还具有高输出精度、极低压差、低静态电流和快速启动等特性。

EUP7917输出很低的噪声电压,应用于需要干净电压源的RF电路是非常理想的,一个旁路噪声的引脚可以用来大大地降低输出噪声。 这款器件为手持式和电池供电的设备特别设计,它提供了与TTL逻辑兼容的使能控制引脚,当使能关断时,功耗下降至几乎为零。

EUP7917采用5引脚SC-70封装,它可以在使用低ESR的陶瓷电容时正常工作,大大节省了PCB板空间,这对手持式无线设备是非常重要的。

EUP7917能提供很宽范围的输出电压。关键特性还包括电流限制、过温关断保护和快速瞬态响应。

EUP7917-300mA, High PSRR Low-Noise LDO 

Description
The EUP7917 is an efficient, CMOS voltage regulator optimized for ultra-low-noise applications. It offers high output accuracy, extremely low dropout voltage low ground current and fast start-up time. The EUP7917 provides a very low noise output, ideal for RF applications where a clean voltage source is required. A noise bypass pin is also available for further reduction of output noise.
Designed specifically for handheld and battery- powered devices, the EUP7917 provides a TTL-logic-compatible enable pin. When disabled, power consumption drops nearly to zero. The EUP7917 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices.
