Micrel
Absolute Maximum Ratings
Absolute Maximum Ratings indicate limits beyond which damage
to the device may occur. Electrical specifications do not apply when
operating the device beyond its specified Operating Ratings.
Recommended Operating Conditions
Input Voltage ................................................................2.5V to 26V
Operating Junction Temperature Range.............. –40°C to +125°C
ENABLE Input Voltage ......................................................0V to VIN
Power Dissipation................................................ Internally Limited
Lead Temperature (Soldering, 5 seconds) ............................260°C
Operating Junction Temperature Range.............. –40°C to +125°C
Input Supply Voltage .................................................–20V to +60V
ENABLE Input Voltage ..............................................–20V to +60V
SO-8 θJA ........................................................................See Note 1
Electrical Characteristics
Limits in standard typeface are for TJ = 25°C and limits in boldface apply over the junction temperature range of –40°C to +125°C. Speci-
fications are for each half of the (dual) MIC5202. Unless otherwise specified, VIN = VOUT + 1V, IL = 1mA, CL = 10µF, and VCONTROL ≥ 2.0V.
