Input voltage as low as 1.5V
400mV dropout @ 1A
Adjustable output from 0.5V
Over current and over temperature protection

10 μA quiescent current in shutdown
Low reverse leakage (output to input)
Full industrial temperature range
Pb Free, Halogen Free and WeEE/RoHS Compliant
The SC4212 is a high performance positive voltage regu-
lator designed for applications requiring very low input
voltage and very low dropout voltage at up to 1 Ampere.
It operates with a VIN as low as 1.5V, with output voltage
programmable as low as 0.5V. The SC4212 features ultra
low dropout, ideal for applications where VOUT is very
close to VIN. Additionally, the SC4212 has an enable pin
to further reduce power dissipation while shutdown. The
SC4212 provides excellent regulation over variations in
line, load and temperature.
Applications
? Telecom/Networking cards
? Motherboards/Peripheral cards
? Industrial Applications
The SC4212 is available in a 3 x 3 MLPD-8 package. The
output voltage can be set via external divider or to a
fixed setting of 0.5V depending upon how the FB pin
is configured.
