ZMR250Q/ ZMR330Q/ ZMR500Q
AUTOMOTIVE COMPLIANT 2.5V, 3.3V AND 5V SOT23 (Type DN)
VOLTAGE REGULATORS
Description
The ZMR250Q/ZMR330Q/ZMR500Q of three terminal fixed positive
voltage regulators feature internal current limit and will shut down
under thermal overload conditions making the devices difficult to
destroy.
Pin Assignments
(Top View)
The circuit design offers an exceptionally low quiescent current, only
30μA for the 2.5V device, ideal for low power applications. The initial
devices in the series regulate to 2.5V or 5V with a drive capability up
to 50mA.
All three devices are designed with space saving in mind and are
available in the small outline SOT23 (Type DN) package. All three
have an input voltage range of at least 20V plus the output voltage.
SOT23 (Type DN)
The ZMR250Q, ZMR330Q and ZMR500Q have been qualified to
AEC-Q100 Grade 1 and are Automotive Compliant supporting
PPAPs.
