Enpirion Power Datasheet

EY1603 40V, Low Quiescent Current,

150mA Linear Regulator

Datasheet

DS-1047

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.

Features

• Wide V_INRange of 6V to 40V

• Adjustable Output Voltage from 2.5V to 12V

• Guaranteed 150mA Output Current

• Ultra Low 18µA Typical Quiescent Current

• Low 2µA of Typical Shutdown Current

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.

•

1% Accurate Voltage Reference

• Low Dropout Voltage of 295mV at 150mA

• 40V Tolerant Logic Level (TTL/CMOS) Enable Input

• Stable Operation with 10µF Output Capacitor

• 5kV ESD HBM Rated

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.

• Thermal Shutdown and Current Limit Protection
