MP20045 – LOWER NOISE, 1A LINEAR REGULATOR
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
(2)
Notes:
Continuous Power Dissipation (TA=+25°C)
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.
