AME8831
150mA Hi-PSRR, Low-Quiescent LDO
with In-Rush Current Control
For USB Application
n Electrical Specifications
Over operating temperature range(TJ=-40oC to +125oC), VIN=VOUT(nom) + 1V, or VIN=VIN(Min) whichever is greater,
IOUT=1mA, VEN=VIN(VENB=0), and COUT=4.7uF, CIN=1uF unless otherwise noted. Typical values are at TA=25oC.

Note1 : VIN(min) = VOUT + VDROPOUT(max)
Note2 : Continuous output current and operating junction temperature are limited by internal protection circuitry,
but it is not recommended that the device operate under conditions beyond those specified in this table for
extended periods of time.
