Note 1: Absolute Maximum Rating is limits beyond which damage to the device may occur. For guaranteed

specifications and test conditions see the Electrical Characteristics.

Note 2: The device is not guaranteed to operate outside its operating rating.

Note 3: Devices are ESD sensitive. Handling precautions recommended.

Note 4: The maximum allowable power dissipation is a function of the maximum junction temperature, TJ, the junction

to ambient thermal resistance, ӨJA, and the ambient temperature, Ta. Exceeding the maximum allowable

power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. The

effective value of ӨJA can be reduced by using a heat sink, Pd(max) = (TJ(max) – Ta) / ӨJA.

Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops -1% below its

nominal value measured at 1V differential.

Note 6: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of

the ground pin current and output load current, IGND = IIN - IOUT for fix output voltage, , IGND = IIN - IOUT +10mA

for fix reference output voltage in full load regulation.

Note 7: VREF ≤ VOUT ≤ (VIN – 1V), 2.25V ≤ VIN ≤ 16V, 10mA ≤ IL ≤ 1.0A.

Note 8: Output voltage temperature coefficient is ΔVOUT (worse cast) / (TJ(max) – TJ(MIN)) where is TJ(max) +125

oC and

TJ(MIN) is 0

oC.

Note 9: For adjustable device and fixed device with VOUT > 2.25V.

Pin Description

Pin Configuration

Pin Description

Enable

TTL/COMS compatible input. Logic high is enable; logic low or open is shutdown

Input

Unregulated input: +16V maximum supply

Ground

Ground: Ground pin and TAB / heat sink are internally connected.

Output

Regulator output

Flag (fixed voltage)

Error Flag (output): Open-collector output. Active low indicates an output fault condition,

if no used, leave open.

Feed Back (adjustable)

Adjustment input: Feedback input. Connect to resistive voltage-divider network.
