LT3021 Datasheet, PDF (1/2 Pages) Linear Technology – 500mA, Low Voltage, Very Low Dropout Linear Regulator

Tripolar Overvoltage Protection for Network Interfaces
LT3021
Description
The LT3021 is a low capacitance transient surge arrestor designed
for protection of high debit rate communication network. Its low
capacitance avoids distorsion of the signal as it has been designed
for T1/E1 and Ethernet networks.
