* For fixed output voltage versions between 1.5V and 5V, add suffix –XX (e.g. MP20045DQ-33 is the 3.3V fixed
output). Contact factory for availability.
** For Tape & Reel, add suffix –Z (e.g. MP20045DQ–Z, MP20045DN–Z);
For RoHS compliant packaging, add suffix –LF (e.g. MP20045DQ–LF–Z, MP20045DN–LF–Z).

Thermal Resistance (4)
QFN8 (3x3).............................50 ......12 ...C/W
SOIC8E..................................50 ......10 ...C/W
θJA θJC
ABSOLUTE MAXIMUM RATINGS (1)
VIN, EN, PG, FB to GND ............... -0.3V to +6V
OUT to GND.........................-0.5V to VIN + 0.5V

Notes:
Continuous Power Dissipation (TA=+25C)
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ(MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD(MAX)=(TJ(MAX)-
TA)/ θJA. Exceeding the maximum allowable power dissipation
will cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.
