Excellent input and load transient response of S-19218

 Excellent transient response

A power supply IC for an automotive device is connected to the IG (ignition) power supply and must provide stable power with excellent transient response even under drastic load and voltage fluctuations.
S-19218 Series responds to this need.
・Input transient response:
     About 1.5 times* (When VIN = 6.0V→13.5V)
     About 2.0 times* (When VIN = 13.5V→6.0V)
・Load transient response:
     About 1.3 times* (When IOUT = 1mA→100mA)
     About 2.0 times* (When IOUT = 100mA→1mA)
(*When compared to other company products with similar functions)

S-19218: Reduces device footprints and costs

 Compatible with small I / O capacitors

From a current and transient response standpoint, power supply ICs using a bipolar process are often connected to an IG (ignition) power supply. However, the large external capacitors they require are a significant disadvantage.
・S-19218 Series permits use of 0.1μF input capacitors and 1.0μF output capacitors.
Since easily available small capacitors can be used instead of high-capacity capacitors, both device footprints and costs can be reduced.



S19218: High power dissipation package TO-252-5S(A)

  Achieves both heat countermeasures and  smaller footprint

S-19218 Series is housed in a TO-252-5S(A) package, which is mounting compatible with the industry standard TO-252-5 package.
The TO-252-5S(A) is a small package that occupies about 35% less board space than the TO-252-5 and is only about half as thick while providing the same level of heat dissipation.
・Under certain operating conditions, S-19218 Series can be substituted for a DC-DC converter to substantially shrink device footprints.
