ELECTRICAL CHARACTERISTICS

Absolute Maximum Ratings †

Supply Input Voltage (VIN) .......................................................................................................................... –20V to +20V

Power Dissipation (PD) (Note 1) ............................................................................................................Internally Limited

Operating Ratings ‡

Supply Input Voltage (VIN) ......................................................................................................................... +2.5V to +16V

† Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of the device at those or any other conditions above those indicated

in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended

periods may affect device reliability.

‡ Notice: The device is not guaranteed to function outside its operating ratings.

Note 1: The maximum allowable power dissipation at any TA (ambient temperature) is calculated using: PD(max) =

(TJ(max) – TA) ÷ θJA. Exceeding the maximum allowable power dissipation will result in excessive die tem-

perature, and the regulator will go into thermal shutdown.

ELECTRICAL CHARACTERISTICS

Electrical Characteristics: VIN = VOUT + 1.0V; COUT = 4.7 µF; IOUT = 100 µA; TJ = +25°C, bold values indicate

–40°C ≤ TJ ≤ +125°C; unless noted.
