tery powered applications.
鈩?/div>
(Vertically Integrated PNP) pro-
cess, the LP2992 delivers unequalled performance in all
specifications critical to battery-powered designs:
Dropout Voltage:
Typically 450 mV
@
250 mA load, and
5 mV
@
1 mA load.
Ground Pin Current:
Typically 1500 碌A
@
250 mA load, and
75 碌A
@
1 mA load.
Enhanced Stability:
The LP2992 is stable with output ca-
pacitor ESR as low as 5 m鈩? which allows the use of ceramic
capacitors on the output.
Sleep Mode:
Less than 1 碌A quiescent current when
ON/OFF pin is pulled low.
Smallest Possible Size:
SOT-23 and LLP packages use
absolute minimum board space.
Precision Output:
1% tolerance output voltages available
(A grade).
Low Noise:
By adding a 10 nF bypass capacitor, output
noise can be reduced to 30 碌V (typical).
Multiple voltage options, from 1.5V to 5.0V, are available as
standard products. Consult factory for custom voltages.
