SC4215J
Very Low Input /Very Low Dropout
2 Amp Regulator With Soft-Start
Description
The SC4215J is a high performance positive voltage regu-
lator 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 1.4V, with output
voltage programmable as low as 0.5V. The SC4215J fea-
tures ultra low dropout, ideal for applications where Vout
is very close to Vin. Additionally, the SC4215J has an enable
pin to further reduce power dissipation while shut down.
The SC4215J provides excellent regulation over variations
in line, load and temperature.
The SC4215J is available in the SOIC-8-EDP (Exposed Die
Pad) package. The output voltage can be set via an exter-
nal divider or to a fixed setting of 0.5V depending upon
how the FB pin is configured.
