(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)
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 200 ppm/C or better temperature stability.
(4)
Without TurboTrans, the minimum ESR limit of 7 m
must not be violated.
(5)
A low-leakage (<100 nA), open-drain device, such as MOSFET or voltage supervisor IC, is recommended to control pin 9. The
open-circuit voltage is less than VI.
(6)
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.
