ESD Ratings

Human body model (HBM) ........................ ±2kV

Charged device model (CDM).................... ±2kV

Recommended Operating Conditions (3)

Supply voltage (VCC)………………… 12V to 32V

MAINSIN

………………………………… 0V to 4V

Maximum junction temp (TJ) .....................125°C

Thermal Resistance (4)

θJA

θJC

SOIC-8

……………...................90...... 45... °C/W

Notes:

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,

θ

JA,

and

the

ambient

temperature, TA. The maximum allowable continuous power

dissipation at any ambient temperature is calculated by D

(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.

3)

The device is not guaranteed to function outside of its

operating conditions.

4)

Measured on JESD51-7, 4-layer PCB.
