See Typical Performance Characteristics curves. Wide supply voltage range 2. C, and limits in boldface type apply over the full operating temperature range. Requires few external components.

The maximum allowable power dissipation at any ambient temperature is calculated using: Output Voltage Survival Note 4. For details, refer to Application Hints. The output voltage is set using two external resistors see.

ESD Rating Note 2. The internal diode can also be turned on if the input voltage. It is recommended that the resis. A 7 pF feed-forward ca. To ensure proper operation, the signal source used to drive.

Package Marking and Ordering Information. Dropout voltage is defined as the input to output differential at which the output voltage drops mV below the value measured with a 1V differential.


If the output is forced above the input by more than a V BE. F is required the amount of capacitance may be in. Schottky diode see below must be used in applications.

If it is used as an input capacitor, no resistor is needed as. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator. It is also important that the turn-on and turn-off voltage sig. Equivalent Series Resistance for stable opera. The output capacitor must maintain its ESR in. Like any low-dropout regulator, the external capacitors must.
