RT9048GSP集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

General Description

The RT9048 is a high performance positive voltage regulator

designed for use in applications requiring ultra low input

voltage and ultra-low dropout voltage at up to 2A. The

feature of ultra-low dropout voltage is ideal for the

application where output voltage is very close to input

voltage. The input voltage can be as low as 1.4V and the

output voltage is adjustable by an external resistive divider

as low as 0.5V. The RT9048 provides an excellent output

voltage regulation over variations in line, load and

temperature. Over-current and over-temperature protection

functions are provided. Additionally, an enable pin is

designed to further reduce power consumption while

shutdown and the shutdown current is as low as 1.5μA.

The RT9048 is available in the SOP-8 (Exposed Pad)

package.
