APPLICATION NOTE C ONSIDE R A T IONS
1. The minimum RSET resistor value is 1k ohm for the current
limit sensing. If this resistor becomes shorted, it will do
permanent damage to the IC.
2. A resistor has been put in series with the gate of the LDO
pass transistor to reduce the output noise level. The resistor
value can be changed to optimize the output transient
response versus output noise.
3. To delay the turn on of the LDO controller output, a
capacitor should be connected between the LDDIS pin and
the +5volts.
The LDDIS input has a 100K pull down
resistor, which keeps the LDO active until this pin is pulled
high. During the power up sequence the capacitor connected
to the LDDIS pin will keep the LDO off until this capacitor,
being charge by the 100K pull down resistor, goes through
the low input threshold level.
4.
. If current limit is not used connect the VS and VC pins
together and to VCC. Do not leave them floating. A floating VS
pin will result in operation resembling a hiccup condition.
