ZMR330 3.3 VOLT MINIATURE VOLTAGE REGULATOR DESCRIPTION The ZMR330 is a 3 terminal fixed 3.3 volt, 50mA, regulator. Internal current limiting and thermal overload protection are included thus protecting the device from some extreme operating conditions. The circuit design offers low quiescent current of 170µA. Making the part suitable for low power applications. The ZMR330 is designed with space saving in mind and the small SOT23 package is ideal where space is restricted. SOT23 FEATURES • 3.3 volt output • 5V to 24V input range • 50mA output current PINOUT • 170 µA quiescent current. • -55 to +125°C operating temperature • SOT23 package APPLICATIONS • Local power supply • Automotive • Industrial TOP VIEW ORDERING INFORMATION DEVICE ZMR330FTA PACKAGE SOT23 REEL SIZE TAPE WIDTH QUANTITY PER REEL 7” 8mm 3,000 DEVICE MARKING • 330 ISSUE 3 - MARCH 2005 1 ZMR330 ABSOLUTE MAXIMUM RATINGS Input voltage -0.6 to 24V Output current 100mA Operating temperature -55 to 125°C Storage temperature -65 to 150°C Maximum junction temperature 150°C Package power dissipation 400mW at TA = 25°C (De-rate to zero at 150°C) The maximum power dissipation for the SOT23 package is calculated assuming that the device is mounted on a FR4 substrate measuring 15 x 15 x 0.6 mm. Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for extended periods, may reduce device reliability.
