Notes:

(1) Specifications are applicable for a power dissipation of 2.5W and are only achievable over a limited range of

VIN - VOUT.

(2) Low duty cycle pulse testing with Kelvin connections required. Changes in output voltage due to heating effects

are covered under the specification for thermal regulation.

(3) 30ms pulse.

(4) Bandwidth of 10Hz to 10kHz

(5) 120Hz input ripple, 1 dB less for each volt increase above 3.3V Min.; COUT & CADJ (for ADJ) = 25µ..

(6) This device is ESD sensitive. Use of standard ESD handling handling precautions is required.
