Automotive-Grade Regulators from Diodes Incorporated Deliver 5V, 8V, or 12V Outputs and Tolerate 60V Battery Transients

Plano, Texas – 30 November, 2017  – The ZXTR2105FQ, ( ZXTR2108FQ ( and ZXTR2112FQ ( ) regulator transistors announced by Diodes Incorporated are qualified to AEC-Q101 standards for high reliability and are product part approval process (PPAP)-capable. Designed to deliver 5V, 8V, or 12V regulated outputs from nominal battery supplies of 12V or 24V, these regulator transistors are well-suited for powering vehicle electronics. These devices can tolerate battery voltage spikes up to 60V, making possible applications that cannot use standard linear regulators.

By monolithically integrating a transistor, Zener diode, and resistor into a SOT23 package, these regulator transistors reduce component count, which minimizes PCB area and increases system reliability by reducing PCB interconnect. The ZXTR2105FQ is targeted at applications that require a 5V ±5% regulated supply from a 12V battery, e.g., for a stable MCU supply within the required 4.7V to 5.3V supply range. The ZXTR2112FQ is aimed at cars and trucks that have 24V batteries but need a 12V ±10% supply for applications such as the VCC supply for gate driver ICs. All these regulator transistors deliver an output current up to 15mA.

The 60V maximum input rating of all these regulators ensures sufficient headroom in the event of transient over-voltage conditions, while their line and load regulation safeguards continuous operation by ensuring transient voltage drops cannot cause latch-up, further contributing to system reliability.

The automotive-qualified ZXTR21xxFQ devices provide a highly reliable and compact solution to common voltage regulator requirements in vehicle electronics and are priced at $0.15 in 10k quantities. Further information is available at
