Description
Sc4215 Very Low Input / Very Low Dropout 2 Amp Regulator With Enable
Manufacturer
Semtech Corporation
Datasheet
The SC4215 is a high performance positive voltage
regulator designed for use in applications requiring very
low Input voltage and very low dropout voltage at up to
2 amperes. It operates with a Vin as low as 1.6V, with out-
put voltage programmable as low as 0.8V. The SC4215
features ultra low dropout, ideal for applications where Vout
is very close to Vin. Additionally, the SC4215 has an
enable pin to further reduce power dissipation while shut
down. The SC4215 provides excellent regulation over varia-
tions in line, load and temperature.
The SC4215 is available in the SOIC-8-EDP (Exposed Die
Pad) package. The output voltage can be set via an
external divider or to fixed settings of 0.8V and 2.5V de-
pending on how the ADJ pin is configured.
