첨부파일 1 IK4993 Preliminary Data Sheet_20170227.pdf


P/N : IK4993
Function : 5.0V/150mA Low-Drop Fixed-Voltage Regulator
Application : Automotive
PKG Type : SOP-8, SOP-20
Competitor : L4993


GENERAL DESCRIPTION

The IK4993 is a monolithic integrated low-drop fixed voltage regulator 150mA with low current consumption.
The regulating output voltage element consists in a p-channel MOS and the regulation is performed regardless of input voltage transients up to 40V. The high precision of the output voltage is obtained with a pre-trimmed reference voltage. The IK4993 is protected against short circuit and an over-temperature protection switches off the IC in case of extremely high power dissipation.
Reset and watchdog make this device particularly suitable to supply microprocessor systems in automotive applications.
