ZMR250Q/ ZMR330Q/ ZMR500Q AUTOMOTIVE COMPLIANT 2.5V, 3.3V AND 5V SOT23 (Type DN) VOLTAGE REGULATORS Description Pin Assignments The ZMR250Q/ZMR330Q/ZMR500Q of three terminal fixed positive voltage regulators feature internal current limit and will shut down (Top View) under thermal overload conditions making the devices difficult to destroy. The circuit design offers an exceptionally low quiescent current, only 30A 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. SOT23 (Type DN) 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. The ZMR250Q, ZMR330Q and ZMR500Q have been qualified to Applications AEC-Q100 Grade 1 and are Automotive Compliant supporting PPAPs. Automotive Point of Load Regulation Features 2.5V, 3.3V and 5V Output Output Current up to 50mA Very Low Quiescent Current (30A) Unconditionally Stable Internal Short Circuit Current Limit Green Molding in SOT23 (Type DN) Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free.

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 +25C and must be linearly derated to zero at T = T = +125C. A J 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.
