lm2941wg-883 National Semiconductor Corporation, lm2941wg-883 Datasheet - Page 9

• Manufacturer Part Number: lm2941wg-883
• Description: 1a Low Dropout Adjustable Regulator
• Manufacturer: National Semiconductor Corporation

Typical Applications
5V to 20V Adjustable Regulator
20158503
Note: Using 1KΩ for R1 will ensure that the input bias current error of the adjust pin will be negligible. Do not bypass R1 or R2. This will lead to instabilities.
* Required if regulator is located far from power supply filter.
** C
must be at least 22μF to maintain stability. May be increased without bound to maintain regulation during transients. Locate as close as possible to the
O
regulator. This capacitor must be rated over the same operating temperature range as the regulator and the ESR is critical; see curve.
1A Switch
20158506
*** To assure shutdown, select Resistor R3 to guarantee at least 300μA of pull-up current when S1 is open. (Assume 2V at the ON/OFF pin.)
