DIA7986中文资料6V,1A,高精度,带PG功能的线性稳压器数据手册DIOO规格书

描述 Description

The DIA7986 is a 1 A ultra-low-dropout regulator with power-good function. The DIA7986 is designed for applications requiring low quiescent current and provides fast line and load transient performance. Additionally, DIA7986 features high Power Supply Ripple Rejection (PSRR) at up to 1 A. \
The DIA7986 operates with an input voltage range from 1.7 V to 6.0 V and the output voltage is adjustable from 0.55 V to 5.5 V. \
The DIA7986 is stable with small ceramic output capacitors, allowing for a small overall solution size. An error amplifier and precision band-gap provide an accuracy of ±2% over temperature. The DIA7986 helps reduce the thermal dissipation during short-circuit events with internal foldback current limit. The device also contains integrated thermal shutdown, current limit, and undervoltage lockout (UVLO) features.
