ZMR250
ZMR500
ABSOLUTE MAXIMUM RATINGS
Input voltage 20V
Package power dissipation SOT23 500mW (Note 3)
(Tatnt)=25 ‘C) T092 600mW
Output current (Io) 200mA
Operating temperature -55 to 125°C
Storage temperature -65 to 150”C
Note:
1.
The maximum operating input voltage and output current of the device will be governed by the maximum
power dissipation of the selected package. Maximum package power dissipation is specified at 25 ‘C and must
be linearly derated to zero at T,~tF1250C.
2. The following data represents pulse test conditions with junction temperatures as indicated at the initiation
of the test Continuous operation of the devices with the stated conditions might excead the power dissipation
limits of the chosen package,
3. Maximum power dissipation, for the SOT23 package, is calculated assuming that the device is mounted on
aceramic substrate measuring 15 x 15 x 0.6mm.
