† 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.

Note 1: Provided that the device is used in the range of IOUT  PD/(VIN - VOUT).

2: The maximum rating corresponds to the lowest value between VIN + 0.3V or +6.5V.

3: The device is mounted on one layer PCB with minimal copper that does not provide any additional cooling.

DC CHARACTERISTICS

Electrical Characteristics: Unless otherwise indicated, VSHDN = VIN, IOUT = 1 mA, CIN = COUT = 0 µF, VIN = 3.5V for

VR < 2.5V and VIN = VR + 1V for VR  2.5V, TA = +25°C
