Recommended Operating Conditions

(3)

Supply voltage (VIN)..................... 2.7V to 5.5V

Operating junction temp. (TJ) ... -40°C to +125°C

Thermal Resistance

(4)

θJA θJC

WLCSP-12 (1.3mmx1.7mm) ... 110... 12 ... °C/W

NOTE:

1) Exceeding these ratings may damage the device.

2) The maximum allowable power dissipation is a function of the

maximum

junction

temperature

(MAX),

the

junction-to-

ambient thermal resistance θ

JA, 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 produces an excessive die temperature,

causing the regulator to go into thermal shutdown. Internal

thermal shutdown circuitry protects the device from permanent

damage.

3) The device is not guaranteed to function outside of its

operating conditions.

4) Measured on JESD51-7, 4-layer PCB.
