ABLIC Launches the S-19516, S-19517 and S-19519 Series Multifunctional All-In-One LDO Linear Regulators for Enhanced Automotive Device Safety

- Simultaneously provide MCUs with high-current supply as well as voltage and operation monitoring -

TOKYO--()--ABLIC Inc. (President: Nobumasa Ishiai, head office: Minato-ku, Tokyo, hereinafter “ABLIC”) today launched the S-19516, S-19517 and S-19519 Series of high-current supply LDO linear regulators (*1), which integrate the power supply voltage monitoring (reset) and operation monitoring (watchdog timer) (*2) functions.

Since the new S-19516, S-19517 and S-19519 Series have power supplies equipped with high-current (500mA) LDO linear regulators, they can resolve any issues that a comparable product using switching regulators would face.

The S-19516, S-19517 and S-19519 Series do not generate noise, and require few external components compared to a switching regulator. Since a single chip comprises the LDO linear regulator, reset IC and watchdog timer, these models have a small footprint and few parts, which simplify circuit design. In addition, the IC’s ultra-low self-current consumption substantially reduces standby current (*3).

Moreover, the S-19516, S-19517 and S-19519 Series comply with the AEC(*)-Q100 (*Automotive Electronics Council) standards for automotive ICs and are also PPAP (Production Part Approval Process)-capable.

(*1) What is an LDO? What is a linear regulator?


(*2) What is a watchdog timer?


(*3) What is standby current?

Standby current is current that flows even when the ignition is turned OFF.

[Major Features]

  1. High output current makes the device capable of handling the high-current demand of recent microcontrollers!
  2. Window mode improves safety
  3. Housed in a small high heat dissipating package
  4. Equipped with an ENABLE pin that can reset the entire IC to standby
  5. Automotive quality
    These series have passed the triple-temperature test (low, normal and high temperature), and meet AEC-Q100 standards—the reliability and quality test defined by the Automotive Electronics Council (AEC). They are also Production Part Approval Process (PPAP)-capable. These factors ensure they are well suited to the harsh environment of automotive applications.

[Application Examples]

Monitoring of constant-voltage power supply and microcontrollers for automotive devices
