(1)
For output voltages less than 10 V, the minimum input voltage is 7 V or (VO + 2) V, whichever is greater. For output voltages of 10 V
and higher, the minimum input voltage is (VO + 2.5) V. See the Application Information section for further guidance.
(2)
For output voltages less than 3.6 V, the maximum input voltage is 10
× V
O . See the Application Information section for further guidance.
(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 100 ppm/
°C or better temperature stability.
(4)
This control pin has an internal pullup, and if left open-circuit, the module operates when input power is applied. The open-circuit voltage
is typically 1.5 V. A small, low-leakage (< 100 nA) MOSFET is recommended for control. An external pull-up resistor should not be used.
See the Application Information for further guidance.
(5)
An external 2.2-F ceramic capacitor is required across the input (VI and GND) for proper operation. Locate the capacitor close to the
module.
(6)
100 F of output capacitance is required for proper operation. See the Application Information section for further guidance.
(7)
This is the typical ESR for all the electrolytic (nonceramic) capacitance. Use 17 m
as the minimum when using max-ESR values to
calculate.
