NAME
FUNCTION
1
SKIP
When
SKIP
= low, the regulator operates in low-quiescent-current skip mode. When
SKIP
= high, the
regulator operates in constant-frequency mode, minimizing output ripple and noise.
SKIP
must be tied
high for input voltages above 3.6V.
Shutdown Input. Drive
SHDN
through an external resistor. When
SHDN
= low, the device turns off. When
current is sourced into
SHDN
through R
EXT
, the device activates, and the
SHDN
pin input current sets the
oscillator’s switching frequency. R
EXT
(k
) = 45000 (V
IN
- 0.69V) / f
OSC
(kHz).
Input Supply Pin. Can range from 2.7V to 5.5V for
SKIP
= high, and 2.7V to 3.6V for
SKIP
= low. Bypass to
PGND with a suitable value capacitor (see Capacitor Selectionsection).
