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 -

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?
An LDO (Low Drop Out) regulator is a linear regulator that can operate at a very low potential difference between the input and output voltage.
A linear regulator is a power supply IC that can output a lower stable voltage from an input voltage.

(*2) What is a watchdog timer?
A watchdog timer (WDT) is a timer that monitors microcontroller programs to determine whether or not they are out of control or have stopped running.

(*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
