Seiko Instruments Releases New Automotive LDO Regulator Capable of 36 V Input Voltage and 250 mA Output Current. The S-19212 Series features low current consumption of 6.5 µA for standby current reduction in automotive applications directly connected to batteries.
Seiko Instruments Inc. (SII) announced the release of the S-19212 Series automotive LDO regulator with 36 V high input voltage and 250 mA output current, featuring a super low current consumption of 6.5 µA and high output voltage accuracy of ±2.0%. The innovative S-19212 Series is the perfect match for automotive use in constant-voltage power supply for ECUs for engines, transmissions and suspensions, Anti-lock Brake Systems, related Electric Vehicle equipment, and Hybrid Electric Vehicle and Plug-in Hybrid Electric Vehicle electronics. Other typical automotive applications include Body ECUs for bodies, headlamps, ITS, and accessories, navigation systems, and audio systems.
The S-19212 Series was specifically developed to meet the demanding high quality requirements for automotive use. The 36 V maximum input voltage (rating 45 V) and the operating temperature range up to 125 degrees C enable operation in high input voltage and high temperature applications such as engines. The selectable output voltage ranges from 2.5 V to 16 V in 0.1 V steps. The packages are the lead-free and halogen-free HSOP-8A, HSOP-6, SOT-89-5, and SOT-23-5. A build-in overcurrent protection circuit limits overcurrent of the output transistor and a built-in thermal shutdown circuit limits heat, and the ON/OFF circuit helps extend battery life. Ceramic capacitors as small as 1.0 µF are available for input and output capacitors. The junction temperature range is from −40 to +150 degrees C.
The S-19212 Series has options available with a thermal simulation service which offers a suggestion of thermal resistance value and recommended wiring ratio to help customers select packages. AEC-Q100 is currently in process, and the application for PPAP approval is available.
