SC4217 Datasheet | SEMTECH

Features Input voltage range from 1.8V to 5.5V - Typical 300m V dropout @ 3A - Adjustable output from 1.24V - Over-current and over-temperature protection - Enable pin - 10µA shutdown current - Full industrial temperature range .. - TO263-5 package, fully WEEE and Ro HS pliant - Very Low Input /Very Low Dropout 3 Amp Regulator With Enable Description The SC4217 is a 3A, high performance LDO designed for use in applications requiring very low input voltage and very low dropout voltage. It operates with an input voltage as low as 1.8V and a programmable output voltage from 1.24V. The SC4217 Features ultra- low dropout, ideal for applications where VOUT is very close to V IN . Additionally, the SC4217 has an enable pin to further reduce power dissipation while shut down. The SC4217 provides excellent regulation over line, load and temperature. The SC4217 is available in a TO263-5 package and is fully WEEE and Ro HS pliant.
