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.

Caution:
Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at conditions between maximum recommended operating conditions and absolute maximum ratings is not implied.
Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time.
(Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling
and transporting these devices.)
Notes:
5. The maximum operating input voltage and output current of the device will be governed by the maximum power dissipation of the selected package.
Maximum package power dissipation is specified at +25°C and must be linearly derated to zero at TA = TJ = +125°C.
6. Maximum power dissipation for the SOT23 (Type DN) package is calculated assuming that the device is mounted on a ceramic substrate measuring
15mm x 15mm x 0.6mm.
