(1)
The minimum input voltage is 2.2 V or (VO + 0.5) V, whichever is greater.
(2)
The set-point voltage tolerance is affected by the tolerance and stability of RSET. The stated limit is unconditionally met if RSET has a
tolerance of 1% with 100 ppm/C or better temperature stability.
(3)
A low-leakage (<100 nA), open-drain device, such as MOSFET or voltage supervisor IC, is recommended to control pin 10. The
open-circuit voltage is less than VI.
(4)
This control pin has an internal pull-up. Do not place an external pull-up on this pin. If it is left open-circuit, the module operates when
input power is applied. A small, low-leakage (<100 nA) MOSFET is recommended for control. The open-circuit voltage is less than
3.5Vdc. For additional information, see the related application information section.
(5)
A 220 F input capacitor is required for proper operation. The input capacitor must be rated for a minimum of 500 mA rms of ripple
current. An additional 22-
F ceramic input capacitor is recommended to reduce rms ripple current.
