150mA Linear Regulator
DS-1047
Datasheet
The Altera® Enpirion® EY1603 is a wide input voltage
range, low quiescent current linear regulator ideally
suited for “always-on” and “keep alive” applications.
The EY1603 operates from an input voltage of +6V to
+40V under normal operating conditions and consumes
only 18µA of quiescent current at no load.
The EY1603 has an adjustable output voltage range from
2.5 to 12 V. The EY1603 features an EN pin that can be
used to put the device into a low-quiescent current
shutdown mode where it draws only 2µA of supply
current. The device features automatic thermal
shutdown and current limit protection.
The EY1603 is rated over the -40°C to +125°C
temperature range and is available in a 14 lead HTSSOP
with an exposed pad package.
