1.5 AMP AND 3 AMP LOW DROPOUT

3.3 VOLTAGE POSITIVE REGULATOR

Please see mechanical

FEATURES

• Low Dropout Voltage and Ground Currents

• High Current Capability

• Built-In Thermal Overload Protection

• Short Circuit Current Limiting

• Output Voltage Tolerance Guaranteed to + 1%

• Available in Multiple Hermetic Package Styles

• Output Current from .75A to 3.0A

DESCRIPTION

This series of +3.3 Voltage Regulators are high current, high accuracy, low dropout regulators

and well suited for systems where extremely low dropout voltages is critical. They feature full

protection against overcurrent faults, reversed input polarity, reversed lead insertion, over tem-

perature operation and positive and negative transient voltage spikes. They are available in a

number of hermetic package styles where critical environmental systems demand high per-

formance.

... Although power dissipation is internally limited, regulation is guaranteed up to the maximum power dissipation of 15W for the OM7670 series and 30 watts for the OM7671 series (See Table 1). Power dissipation is determined by the input/output differential voltage and the output current. Guaranteed maximum power dissipation will not be available over 3 ...
