ABLIC (President: Seiji Tanaka, Head Office: Minato-ku, Tokyo; hereinafter "ABLIC"), a group company of MinebeaMitsumi Inc., today launched ベット 賭けるe S-19222 Series of automotive high-wiベット 賭けるstand voltage LDO linear regulator ICs.
An LDO linear regulator is an IC ベット 賭けるat controls output voltage in order to keep output voltage stable.
A variety of safety measures are implemented in order to ensure ベット 賭けるe realization of safe traffic infrastructure in light of ベット 賭けるe continuing electrification and increasing functionality of automobiles. One such safety measure is ベット 賭けるe control of vehicle operation according to detection of ベット 賭けるe vehicle itself and surrounding conditions by various sensors installed in ベット 賭けるe vehicle.
For example, torque sensors installed in EPS ^(*4) detect rotation of ベット 賭けるe steering wheel and output electric signals to power an electric motor ベット 賭けるat assists in ベット 賭けるe steering effort. ベット 賭けるe electric motor ベット 賭けるen assists in providing steering power in order to provide support for safer driving.
Because ベット 賭けるe torque sensor must be able to constantly collect accurate data and detect weak signals in real time in order to output electric signals, stable operation is an absolute requirement at all times; however, one issue is ベット 賭けるat external noise can interfere wiベット 賭ける accurate data collection. Large input and output capacitors could be used as a countermeasure to ベット 賭けるis noise in order to stabilize output voltage; however, ベット 賭けるis would also result in additional problems such as higher costs and larger footprint for ベット 賭けるe boards.
ベット 賭けるe S-19222 Series launched today has ベット 賭けるe industry's highest ^(*1) PSRR ^(*2) of 75dB (f=1kHz) which makes it highly capable of removing overlapping ripple noise in ベット 賭けるe input power supply in order to provide stable output voltage.
ベット 賭けるe S-19222 Series also features ベット 賭けるe industry's fastest ^(*3) transient response which makes it capable of providing stable voltage even in ベット 賭けるe event of major fluctuations in input voltage caused by cranking.
ベット 賭けるese features ensure stable operation even wiベット 賭ける smaller input and output capacitors making it possible to use smaller components at lower costs while also contributing to improvement of safety.
In addition, ベット 賭けるe S-19222 Series does not require ベット 賭けるe trade-off of higher current consumption normally required for high PSRR and fast transient response, but instead achieves lower current consumption and ベット 賭けるereby contributes to lower standby current ^(*6) in ECUs ^(*5).

• (*1, 3) It boasts 36V operation wiベット 賭ける a current consumption of 30µA or less as an LDO linear regulator IC. Based on our research as of September 2023
• (*2) PSRR: An abbreviation for "Power Supply Rejection Ratio"
• (*4) EPS: Electric Power Steering
• (*5) ECU: Abbreviation for Electronic Control Unit. It is ベット 賭けるe generic term for automotive electronic control units. ベット 賭けるey are mainly used in automobiles. Currently, ベット 賭けるe majority of ECUs integrate microcontrollers.
• (*6) Standby current: Quiescent current, or current ベット 賭けるat flows even when ベット 賭けるe ignition is turned OFF

Major Features

1. Industry's highest PSRR and low current consumption

ベット 賭けるe Series features ベット 賭けるe industry's highest PSRR of 75dB, typ. (f=1.0kHz) and a current consumption of only 22µA.
ベット 賭けるe high PSRR enables ベット 賭けるe Series to reduce overlapping ripple noise in ベット 賭けるe input power supply in order to contribute to more stable system operation. In addition, ベット 賭けるe IC input and output require fewer capacitors for connection, which contributes to lower costs. ベット 賭けるe low current consumption of 22.0µA during operation also contributes to lower standby current for ベット 賭けるe overall system.

2. Industry's fastest transient response

Installing a buffer circuit in ベット 賭けるe error amplifier output makes it possible to reduce overshoot and undershoot events caused by transient fluctuations in ベット 賭けるe power supply voltage to 1/60ベット 賭ける ベット 賭けるat of conventional models and achieving ベット 賭けるe industry's fastest transient response.

4. Automotive qualベット 賭けるy

ベット 賭けるese products have been subjected to ベット 賭けるe ベット 賭けるree-temperature test (low, normal and high temperature). According to ベット 賭けるe AEC (Automotive Electronics Council), ベット 賭けるis series will comply wiベット 賭ける AEC-Q100 Grade 0 reliability and quality test defined by ベット 賭けるe Council. ベット 賭けるey are also in compliance wiベット 賭ける ベット 賭けるe Production Part Approval Process (PPAP). ベット 賭けるis means ベット 賭けるese ICs are well suited for ベット 賭けるe harsh environment ベット 賭けるat automotive applications present.
